I would not have answered the door. This doesn't change that when they cross the threshold resisting and grabbing a gun instead of complying to save your life just makes sure you dead. Live, get the body cam, sue. Stop being stupid.Did nobody watch the body cam? His mistake was definitely opening the door. They asked him outside because it was the ONLY legal way to arrest him, since they did not have a warrant. It wasn't until the dumbass rookie grabbed him that resistance started. And the fight wasn't at the door, it was inside the living room of the house that the cops had no warrant to enter.
Now, the important part here shows how most of you have accepted the fact that the government has made you their slave, too afraid to fight for your rights. Generally, a cop will not end up in prison if they shoot you, even illegally, and you all accept that under the idiot premise that cops are mostly 'good'.
Being dead and right is not better than being alive and right then getting paid. Especially when they will not go to jail because the man grabbed a gun.
