If they suspected him of being on PCP, Old...I can tell you from personal experience why they didn't want to tackle him. Myself, a very large doorman and two police officers attempted to subdue one much smaller guy who was on PCP and it was brutal. This little guy literally beat the hell out of all four of us...it was like he had super human strength. The only way we managed to finally get him in cuffs is the doorman tackled him off the landing we were fighting on...down about three feet onto a sidewalk and knocked the wind out of him long enough for one of the cops to slap cuffs on him. When I was called to court to testify against the guy the jury was looking at the police, myself and the doorman...and then at the little guy and you could see it in their faces that they couldn't believe that we'd have a problem overwhelming him physically. It was rather embarrassing actually.
I'm no expert, but the guy didn't look like he was on PCP. They're usually more erratic; he wouldn't have been calmly walking back to his car with his hands in the air.
Sorry about your PCP experience. I know some cops who've dealt with it and I know it is unbelievable.
Someone on PCP just looks a little "dazed", Old...hard to tell until the you know what hits the fan. Trust me though, someone who's on that stuff is not someone you want to have a confrontation with because they literally don't seem to feel pain and are crazy strong.
Killing the guy instead of tackling him, regardless, isn't actually supposed to be an option, though.
A criminal living who's a danger to the people who are with you, and various other randoms he may cross before being stopped shouldn't be an option. For all those officers knew, they could have been the only thing stopping a killing spree. It's not like she woke up this morning and said "I'm going to shoot some random guy today!". I highly doubt any Police Officer WANTS to shoot someone, but sometimes they have to, and other times it's hard to identify WHEN you have to apply deadly force, yet not doing so could cost OTHER lives.
He was only a danger in their minds. Nothing the guy did indicated he was a danger except that he was big, black, and not doing what they said.
As a teacher, I can tell you that when you lose control of your class, it is the scariest button to push. Now, I realize that a student telling you that you can **** yourself and deciding to be boss of your classroom, instead of leaving as instructed, is NOT life threatening. However, the instinct to retain authority is the same, I'd bet anything. Escalation is the immediate reaction.
