How is it at all relevant that he was an LGBT activist, aside from muh identity politics. Is it believed the police were targeting a gay?
They weren't targeting anyone. They were responding to a call that he was carrying a gun. Turns out he was carrying a knife, and when they tried to get him to drop the weapon, he dared them to shoot him. They obliged.
That's no excuse to shoot him dead. They could've easily neutralized him and contained the situation without taking his life. This is simply excessive use of force.
And how do you propose they do that without being stabbed?
There's this amazing thing called the human body and there are many places on it where a person may be shot that'd inflict enough pain to neutralize them without inflicting a fatal wound. A competent, well-trained police officer would've been easily capable of making such a shot at that range without endangering himself either.
LOL.
It's true. Cops over here are trained to shoot to immobilise rather than kill; hitting the legs or arms.
