Welcome to the lead. I'm Jake Tapper. We begin today with the national lead this afternoon.

Phelonus Floyd gave emotional testimony about his big brother George Floyd in the prosecution of former Minneapolis police officer Derek Chauvin.

This all comes as the nation is grappling with multiple new deadly interactions with police just in the last day or so.

The first about 10 miles from where this trial is being held in a suburb of Minneapolis, Brooklyn Center,

where another black man was killed by police. This afternoon, police in that town released the body cam video showing 20-year-old Dante Wright during a traffic stop yesterday,

seeming to resist arrest and try to escape in his car during which he was shot and ultimately killed.

The chief of police said today that he believes the police officer accidentally discharged her gun, meaning instead to fire her taser.

Last night hundreds of people protested Wright's death in Minneapolis, some through projectiles of police, one of whom was injured to the Minnesota National Guard has been deployed.

Additionally, this afternoon, President Biden is calling for call, saying there's no justification for violence.

Also, in Georgia, overnight, three police officers were shot when a driver and a passenger began shooting them during a car chase.

The officers survived, thankfully, but one of the suspects in the car is dead.

Our correspondence are covering all these stories.

Let's start with CNN's Adrian Broadess in Minnesota, where 20-year-old Dante Wright was shot and killed.

And today, the chief of police in Brooklyn Center, Minnesota, released this body cam footage, said he believes this was an accidental discharge, the officer meant to fire her taser instead.

Before we play this video, we have to warn you it is disturbing to watch.

Adrian, we hear the officers say taser, taser, taser, taser, and then she fires her gun, not her taser, and then curses and says, I shot him.

What did the police chief have to say about this video and why did he release it?

Well, start with the why. The chief said he released it because he wanted to be transparent. This is unprecedented, especially here in the state of Minnesota, for a department to release body cam video so quickly.

But he felt he owed it to the public, he felt he owed it to the community, especially members of the community that you see outside of the police department right now.

These are some of the same people who showed up here last night protesting the officer's actions.

And in full transparency, he is calling this an accident.

He said she thought she was reaching for her taser because in that video, you hear her saying taser, taser, taser, which is what officers are supposed to do.
