By saying he would be alive if he wasn't high and in the street, you are putting the blame on him.

He shouldn't have been high and running in the street with a knife, but that shouldn't lead to his death at the hands of a cop. There is no excuse for the cop killing him.

Next thing you know, some of you will be defending a cop who kills a guy who was driving drunk and is mouthing off. I mean, he wouldn't be dead if he was sober and polite.
