And back to what I was saying originally. I'm afraid they'll use (be required to use) this instead of taking more decisive action, such as killing the guy while the rest of us are put at risk.
It's really simple and some activist have come to understand this after some police departments have taken then through some training - if they're compliant, no problem. Act like a dumbass, suffer dumbass consequences. I'm kind of for making sure dumbasses suffer dumbass consequences instead of sticking it to the rest of us to save these people. They'll just go out and do it again. A leopard doesn't change it's spots as a state trooper explained to me.
