What's happening here ?

Taylor's boyfriend fired the first shot , he got her killed .

Is there something seriously wrong with you ? When the Police say "Freeze" you don't pull out a gun and start firing ! When you get pulled over on the street , you don't jump out of the car and start swinging ! It's not Rocket Science .

They didn't announce themselves, so how could they know it was them?

OK , unfortunate victim of the American Education system , how do you know they didn't ? Criminals lie it's what they do .

The police did announce, twice even though they were not reuired to.

proof?

"The Louisville police officers involved in Breonna Taylor’s shooting death “knocked and announced” themselves — and did not execute a “no-knock warrant” as previously believed, Kentucky’s attorney general said Wednesday."

Michael brown was attempting to wrestle the officerc gun away from, possibly ti kill him.

So your saying the police have to let someone shoot them because of the second amendment?

Ok, because every man has a right to defend himself, even police.
