They're trying to rewrite the incident that happened in Ohio ("oh the girl with the knife was DEFENDING herself and yet the cop killed her, I thought we were allowed to defend ourselves" even though the crazy sheboon attacked the girl in pink AFTER the cop yelled to drop the weapon).
Also, what the fuck is with people going "he should have used his taser, he didn't have to use a gun"? From what I know -which granted, isn't much- having an armed assailant lunge at someone with a weapon with the intent to do harm to them has escalated the event past the point where a taser would actually do something useful in the situation.
