Obama urges mayors to review police use of force after Floyd's murder.

247 - "I urge each mayor to review the use of police force and make the necessary changes," said Obama, who also cited a report proposing police reforms.

According to the former president, "several mayors and other elected officials" read the draft, "but after that, there wasn't enough commitment" to make changes.

Obama, in his testimony, also supported young black people who have "witnessed much violence" at the hands of authorities for so long, reports the UOL.

"You should be able to learn and make mistakes and live a life of joy without worrying about what will happen if you go out to a store, go for a run, drive down the street, or watch birds in the park," he declared.

Floyd died after a white police officer, Derek Chauvin, suffocated him with his knee for nearly eight minutes. The incident was captured on video by a bystander.

Minnesota Attorney General Keith Ellison, who is leading the prosecution in the case, will ask that Chauvin be charged with second-degree murder.

Chauvin was transferred to a maximum security prison. Derek was arrested on Friday (29), in Minneapolis. He is one of four police officers suspected of involvement in Floyd's death. And, so far, the only one charged: for manslaughter, when there is no intent to kill.

According to the Associated Press news agency, over his 19-year career, Chauvin was the subject of nearly 20 formal complaints and two letters of reprimand. Most were dismissed.

Thousands of people have been protesting for almost a week in various cities across the United States against racism and police violence. The outrage sparked by Floyd's death has spread throughout the country.
