A white officer who killed a black man after apparently mistakenly grabbing his gun instead of his Taser has turned himself in to police.
Robert Bates, 73, has been charged with manslaughter for killing Eric Harris, 44, during a sting operation over gun sales in Tulsa, Oklahoma.
His lawyer said the charges were "unwarranted" as he and Mr Bates left the police station.
His client was released on a $25,000 (£16,900) bond.
Mr Bates served as a reserve deputy in Tulsa County Sheriff's office, a volunteer position, since 2008.
He is also chief executive of an insurance firm and a major donor to the Sheriff's office.

The manslaughter charge carries a prison sentence of up to four years if Mr Bates is convicted.
A video of the 2 April incident, released at the request of the victim's family, shows Mr Harris being chased and brought to ground before he is shot.
A gunshot is heard and a man says, "Oh, I shot him. I'm sorry."
Mr Harris is heard calling out "He shot me, oh my God!"
He later died in hospital.
It was the second time in a week a videotaped fatal shooting of a black man has provoked an outcry.
Last week Walter Scott, an unarmed 50-year-old, was shot in the back and killed in South Carolina.
The protests that followed that incident continued months of demonstrations about police use of force, ever since a black unarmed teenager was shot dead in Ferguson, Missouri, last summer.

Colleagues say the former Hot Lotto security boss was "obsessed" by rootkits
The former security boss of a lottery in the US has been charged with fraud after allegedly hacking the computer that picks the winning numbers.
Eddie Raymond Tipton was the security director for the Multi-State Lottery Association when he was arrested in January by the Iowa Division of Criminal Investigations.
Prosecutors said he had been caught on CCTV buying the winning ticket. The $14.3m (£9.5m) prize was never claimed.
Mr Tipton denies the charges.
It is alleged the security camera in the lottery room stopped recording
Citing court papers filed by prosecutors in the case, the Des Moines Register said the 51-year-old "may have inserted a thumb drive into a highly locked-down computer that's supposed to generate the random numbers used to determine lottery winners".
The offline computer is housed in a glass room and in theory can only be accessed by two people at the same time. It is also constantly monitored by a video camera.
It is alleged Mr Tipton used his position as security director to change the video camera settings and record only one second in every minute. This would have given him enough time to enter the room and plug a thumb drive into the computer.
On that drive, according to the prosecution, was a rootkit: a stealthy computer program designed to do a specific task and, in this case, then erase itself.
That task was to predetermine the winning lottery numbers for the draw that Mr Tipton was to later buy the winning ticket for.
Mike McLaughlin, senior analyst at computer security company First Base, said the allegation might sound farfetched but was plausible.
He told the BBC: "It is entirely possible to code a rootkit on a USB drive which could interfere with software on a computer then delete itself.
"It would only take a second to run once plugged in.
"However, this can leave traces on the infected machine if you know where to look."
As a member of staff, Mr Tipton was not allowed to win the lottery himself.
The court filings suggest there was an attempt to claim the prize just hours before it was scheduled to expire by a company incorporated in Belize.
If found guilty of the two charges of fraud, Mr Tipton faces up to five years in jail and a fine of up to $7,500.
Hillary Clinton made her first stop on the Iowa-Illnois border at a coffee shop
Hillary Clinton has begun campaigning in Iowa, as the former secretary of state looks to win over voters in the first primary season contest.
Mrs Clinton plans to visit a community college as well as hold a round-table discussion with students and teachers in Monticello.
Her first stop after a road trip from her home in New York was in a coffee shop in the town of Le Claire.
Mrs Clinton came third in the state's 2008 caucus.
Her campaign has said she will stick to small gatherings in Iowa to better connect with voters ahead of a more formal rally.
In a fundraising email on Monday, Mrs Clinton, who was considered a frontrunner before she announced, told supporters she would "work my heart out to earn every single vote".

"It's great!" was Mrs Clinton's response to a reporter who shouted "what's it like to be back in the game?" as she emerged from a more than hour-long chat with a half dozen students and teachers at a small community college in Iowa.
Talking to small groups like this is the big idea of the Clinton campaign - getting as close as she can to what her aides call "everyday Americans".
On Wednesday she will continue her "listening tour" across Iowa.
We will have to wait until May for anything bigger, when reporters might hear more than two shouted words.
Republican candidates are already focusing on Mrs Clinton.
Announcing his own 2016 campaign on Monday, Florida Senator Marco Rubio attacked Mrs Clinton as "a leader from yesterday who wants to take us back to yesterday".
Among those Mrs Clinton spoke to at the Jones Street Java House was Le Claire Mayor Bob Scannell, an independent.
"I always vote for the person who I think will do best for the country, and she has my vote," Mr Scannell said.
Mrs Clinton announced she was running for president on Sunday in a video on her website, then left in a 1,000-mile (1609-km) road trip to Iowa, in a van nicknamed "Scooby" after the cartoon show Scooby-Doo.
Posters - of an unclear source - appeared near the Clinton campaign headquarters on Sunday
Her campaign advisers have set a goal of raising $100m (£68m) for the primary campaign, initially from smaller donors.
Iowan will vote to nominate candidates for each party in January 2016, nine months from now, but Mrs Clinton and three major Republican candidates have already declared they will be running.
SpaceX has narrowly failed in its latest bid to retrieve a rocket booster intact, after a successful launch.
The US rocket made it back to an ocean platform but landed "too hard" to survive, SpaceX CEO Elon Musk tweeted.
The capsule borne by the rocket is heading to the International Space Station (ISS), carrying groceries - including an Italian espresso maker.
By retrieving rockets and recycling them, Nasa contractor SpaceX hopes to slash the cost of space travel.
A later tweet by Mr Musk said the rocket had apparently "landed fine, but excess lateral velocity caused it to tip over post landing".
Images accompanying the tweet appeared to show the rocket toppling over on the platform.
Despite this, the company will be hugely encouraged. The experimental work is making progress.
The firm hopes a successful landing would demonstrate that normally disposable rockets can be refurbished and reused.
It could also point to new ways of bringing spacecraft back down to Earth in general.
The booster finds the platform and is vertical and slowing on approach The Falcon first-stage very nearly pulls it off "Excess lateral velocity caused it to tip over post landing" The platform, 300km north-east of the Cape, was slightly damaged in a previous landing attempt
In January, the first attempt to land the leftover rocket on the ocean platform ended in a fiery explosion when the booster again hit the platform too hard.
Another attempt, in February, was called off because of choppy waters - but the rocket did practise its manoeuvres by slowing itself to a hover over the ocean.
The Falcon 9 rocket, carrying the capsule nicknamed Dragon, launched from Cape Canaveral air force station in Florida on Tuesday afternoon.
The supply ship, carrying more than 4,000 lbs (1,800 kg) of groceries and equipment for the orbiting laboratory, is expected to reach its destination on Friday.
SpaceX was hired by US space agency Nasa to supply the ISS after the retirement of the space shuttle.
Salvage crews managed to retrieve many of the remains from the USS Oklahoma
The remains of nearly 400 US servicemen killed at Pearl Harbor are to be exhumed so they may be identified and given individual burials, the US says.
The sailors and Marines were aboard the battleship USS Oklahoma when it was struck by Japanese torpedoes in 1941.
Their remains were buried together in Hawaii. The identification effort will use advances in forensic and DNA testing, US defence officials said.
Japan's attack on the US base at Pearl Harbor drew the US into World War Two.
The Oklahoma was one of several warships targeted by Japanese submarines and aircraft in the surprise assault on 7 December 1941. More than 2,400 people were killed.
US department of defence officials said the identification effort would be aided by advances in forensic science and technology, as well as by genealogical help from family members.
Survivors of the attack return to a new memorial in Hawaii
"While not all families will receive an individual identification, we will strive to provide resolution to as many families as possible," Deputy Secretary of Defence Robert Work said in a statement.
Only the remains of 35 of the 429 sailors and Marines killed aboard the USS Oklahoma have been identified so far.
The rest of the remains - retrieved during salvage operations from 1942 to 1944 - have been buried in caskets, marked as "unknown", at a national cemetery in Hawaii.
Tom Gray told the Associated Press news agency that his family had waited more than 70 years to give a proper burial to the remains of his cousin, Edwin Hopkins, who was killed aboard the Oklahoma.
While it was an honour for his cousin to have been buried at a national cemetery, he said: "I also think a boy gives up his life at 19 years old and ends up in a comingled grave marked as 'unknown' isn't proper."
The Pearl Harbor attack drew the US into World War Two
A former Blackwater guard has been sentenced to life in prison and three others to 30 years over the killing of 14 Iraqi civilians in 2007.
Nicholas Slatten and three others were convicted last year for the killings in Baghdad's crowded Nisoor Square.
A further 17 Iraqis were injured as the private contractors opened fire to clear the way for a US convoy.
The shootings sparked international outrage and a debate over the role of defence contractors in warfare.
Slatten faced a charge of murder, while the other men faced multiple counts of manslaughter, attempted manslaughter and using firearms while committing a felony.

In a court in Washington DC, Paul Slough, Evan Liberty and Dustin Heard were all sentenced to 30 years in prison for their involvement in the killings.
The men had claimed that they were under fire from insurgents but prosecutors successfully argued what happened was an unprovoked ambush against civilians.
Dozens of victims and witness were flown from Iraq to the US for the trial.
Video monitors in the courtroom showed photos of the dead and wounded, and images of cars shot at and blown up with grenade launchers fired by the guards.
Mohammad Kinani Al-Razzaq's nine-year-old son Ali was killed in the attack.
A picture of the boy smiling was shown on court monitors as Mr Razzaq said: "What's the difference between these criminals and terrorists?''
The sentences were announced following a day-long hearing in which the defendants reaffirmed their innocence and their lawyers unsuccessfully argued for leniency.
Prosecutors argued that the sentences be made even harsher because the ex-guards had never expressed any remorse.
But US District Judge Royce Lamberth rejected both requests.
"Based on the seriousness of the crimes, I find the penalty is not excessive," Judge Lamberth told the court.
Responding to this, Slatten said: "The verdict is wrong, you know that I am innocent, sir."
Meanwhile, Slough's wife, Kirsten, told the BBC her husband made "reasonable judgements based on extensive training and experience".
"He certainly wished things happened differently... But he has not once told me that he thinks he made a wrong decision," she added.
US soul singer Percy Sledge, famed for his song When a Man Loves a Woman, has died aged 74.
Steve Green from talent agency Artists International Management Inc confirmed to the BBC that he died at his home in Baton Rouge, Louisiana, on Tuesday.
"He was one of my first acts, he was a terrific person and you don't find that in this business very often," said Green. "He was truly a standout."
Sledge had surgery for liver cancer in January 2014 but soon resumed touring.
Percy Sledge died at home in Baton Rouge
Sledge's debut single When a Man Loves a Woman reached the top 10 twice in the UK and topped the US Billboard chart for two weeks in 1966, when it also got to number four in the UK chart.
During an interview for the the 2013 documentary Muscle Shoals, he recalled his first recording of it.
"When I came into the studio, I was shaking like a leaf. I was scared," he said, adding that it was the "same melody that I sang when I was out in the fields. I just wailed out in the woods and let the echo come back to me".
'Signed away the rights'
He told BBC Radio 6 Music's Craig Charles in a 2011 interview that he came up with the melody for When A Man Loves A Woman, but signed away the rights of the song to Calvin Lewis and Andrew Wright, because "I didn't know any better".
"I had the melody in my mind so I gave that song to them," he said, adding they then created the lyrics.
Sledge did not contest the agreement, saying: "I felt like if God fixed it in my mouth to give it to them I won't change anything about it.
"I'm satisfied with what I wrote but I cut my kids out of so much because I gave it to someone else - I just wasn't thinking."
Music producer David Gest was among those paying tribute to the singer.
"I am so saddened by the death of my good friend Percy Sledge. I was fortunate enough to have him perform on three of my legends of soul tours and he was absolutely amazing to watch, be it singing When A Man Loves A Woman or Dark End Of The Street," Gest told BBC News.
"Percy was one of the great performers and a man that knew the true meaning of the word 'soul'. Sleep well my friend."
BBC Radio 2 DJ Tony Blackburn added his feelings to those paying tribute on Twitter, and said: "Sad to hear that Percy Sledge has died. I wonder how many times I've played When A Man Loves A Woman. RIP."
Musician Bootsy Collins paid tribute on his Facebook page with the words: "Just lost another legend funkateers, Mr Percy Sledge."
Sledge performed at his induction into the Alabama Music Hall of Fame in March 2010
Paul Gambacini told the BBC that When a Man Loves a Woman was "one of the all time classic songs".
"This was the essence of soul, dripping with feeling. It never had a time, it was in a world of its own, so it was timeless," he added.
The track reached number two when it was re-released in the UK in 1987 after appearing in Oliver Stone's film Platoon, and was featured in several other films such as The Big Chill, The Crying Game and a 1994 Meg Ryan drama named after the song itself. It was also the soundtrack to a Levis advert in 1987.
'Transcendent moment'
It was the first US number one recorded at Alabama's Muscle Shoals studio, where Aretha Franklin and the Rolling Stones would later record.
The track also scored a first gold disc for Atlantic Records, whose executive Jerry Wexler called the song "a transcendent moment" and "a holy love hymn."
It remained Sledge's biggest hit and helped sustain a long touring career in the US, Europe and South Africa, averaging 100 performances a year. His other chart successes included Warm and Tender Love, It Tears Me Up and Take Time to Know Her.
The song found new life in 1991 when Michael Bolton's cover of the song topped the Billboard chart.
Before his music career, Sledge worked in the cotton fields around his hometown of Leighton in northwest Alabama, before taking a job as a hospital nurse in the early 1960s.
A patient heard him singing while he worked and recommended him to record producer Quin Ivy.
The singer was inducted into the Rock and Roll Hall of Fame in 2005 and was a member of the Alabama Music Hall of Fame and the Louisiana Music Hall of Fame.
President Obama says the Iraqi forces are now better trained and equipped than they were
US President Barack Obama has offered Iraqi PM Haider al-Abadi $200m (£135m) in humanitarian aid on his first official visit to Washington.
Mr Abadi had been expected to ask for more arms to fight Islamic State militants but made no request.
The humanitarian aid is to help Iraqis displaced by the militants.
President Obama said Iraqi troops, backed by the US-led coalition, had now recovered about one-quarter of the territory in Iraq seized by the group.
Iraqi forces are getting better equipped and trained since President Abadi was elected to power seven months ago, Mr Obama added.
Mr Abadi said that the US-led air strikes, increased arms and training had helped to push back Islamic State (IS) forces.
But, he added, "we want to see more". The Iraqi leader was expected to seek Mr Obama's help to acquire billions of dollars of advanced US weaponry, including unarmed surveillance drones, attack helicopters and ammunition.
Shia militia have played a prominent role in the Iraqi government's attempts to regain territory
The two leaders also discussed Iran's involvement in battling IS, with President Obama stressing the importance of coordinating activities "through Iraq".
Shia militias believed to be backed by Iran have been playing a major role, but US officials have reportedly demanded their withdrawal from Anbar, Iraq's biggest province, where fierce fighting is currently taking place.
Last week, Mr Abadi launched a campaign to drive IS out of Anbar. The militants responded with a renewed onslaught on the provincial capital, Ramadi.
Mr Abadi's visit to Washington is his first since he took over from Nouri al-Maliki after elections last year.
Nine school officials in Atlanta, Georgia, have been sentenced to prison following convictions for participating in an exam cheating scandal.
Judge Jerry Baxter called the case "the sickest thing that's ever happened in this town".
Three of those convicted received 20-year sentences, far harsher than the penalties asked for by the state.
Evidence of cheating was uncovered at 44 schools with nearly 180 officials involved.
The state-led investigation shocked the city when it discovered that officials at the city-run schools had encouraged teachers to change students' answers in order to demonstrate educational progress.
Thos convicted of 20-year sentences will serve seven years behind bars and 13 years on probation.

Several more received five-year sentences, but will spend only one or two years in prison.
Two others received weekend jail time and home confinement.
Some were also ordered to return the bonuses that they had been given based on the improved test results.
Prosecutors had argued that the plot was a "cleverly disguised conspiracy" to manipulate test scores.
There were several outbursts from the defendants and their lawyers during sentencing.
"You sit down or I'm gonna put you in jail," said Judge Baxter to one of the dozen lawyers in court.
"You keep yelling at me, Judge," the lawyer responded.
Many Cubans hope their country will benefit from more foreign investment
Cuba has welcomed as "fair" a US decision to remove it from a list of state sponsors of terrorism, saying it should never have been on the list in the first place.
The move comes amid a normalisation of ties between the US and Cuba.
The Caribbean country's presence on the list alongside Syria, Iran and Sudan was a sticking point for Cuba during talks to reopen embassies.
A US trade embargo against Cuba remains and can only be ended by Congress.
Mr Obama met Cuban President Raul Castro at the Summit of the Americas in Panama last week, four months after he announced a historic thaw in ties with the communist island nation.
The US president said on Tuesday that the government of Cuba had "not provided any support for international terrorism" over the past six months.
Handshakes and optimism in Panama City

He added that it had "provided assurances that it will not support acts of international terrorism in the future".
A statement from Josefina Vidal, Cuba's top diplomat responsible for dealing with the US, said: "The Cuban government recognised the fair decision made by the president of the United States to eliminate Cuba from a list that it never should have been included on, especially considering our country has been the victim of hundreds of acts of terrorism that have cost 3,478 lives and maimed 2,099 citizens."

This decision is the most concrete step to date taken by the US government to try to dismantle the structures that prevented a normal relationship between both countries for decades.
And it carries a lot of weight too, because it officially changes the way the US government has viewed Cuba since 1982.
The White House now believes Cuba does not support rebel groups such as Farc or ETA and - more importantly - it thinks the government will not do so in the future.
This is a significant message of confidence by the Obama administration towards the Cuban government.
In Havana, ordinary Cubans welcomed the move. Erlinda Geroncelle told Associated Press: "We are not terrorists, just the opposite. We are supporters of peace and tranquillity, and good things for all."
Sara Pino told Reuters: "It's time that Obama realised that Cuba is not what they say the world over. It's time to re-establish ties between Cuba and the United States."
Cuba was first placed on the state department list in 1982, for what the US called efforts "to promote armed revolution by organisations that used terrorism".
The US believes Cuba had long provided a safe haven for members of the Basque separatist group ETA and Colombia's Farc guerrilla group, according to its 2013 Report on Terrorism.
White House press secretary Josh Earnest said the US still had differences with Cuban policies and actions, but they were not "relevant" to the terror list.
Republican Senator Marco Rubio, a candidate for the US presidency, condemned the White House decision, saying Cuba remained a state sponsor of terrorism.
