Derek Chauvin, the ex-police officer who leaned his knee on George Floyd's neck until the man died, was charged with third-degree murder and manslaughter on Friday. The charges, announcedby Hennepin County Attorney Mike Freeman, came after five days of protests in Minneapolis, and hours after CNN journalist Omar Jimenez and his crew were arrested while covering the protests.

"I'm so upset, so angry, so scared and so worried," WGBH's Callie Crossley told Boston Public Radio on Friday, noting that she fears for her own nephew, and "all the other young black men just minding (their) own business, who can't do anything without being deemed suspicious."

Crossley said the Floyd killing left her with a level of rage beyond anything she had felt before, and caused her to start the past few days with gospel music to lift her up.

"I've looked at that video, it's just taken me to heights unknown," she said.

The officer, Chauvin, who is seen in the video leaning on Floyd's neck, has a record of conduct complaints, but has never been prosecuted.
