Didn't we already have a thread on this, or am I mixing up boards?
1) The stop was justified. The cop knew his lights were brighter than typical and sometimes confused other drivers--he was only giving warnings, not tickets.
Not ONLY warnings. Warnings, tazings and shootings.
2) This kid forgot his wallet with his license and was trying to bullshit his way out of a ticket based on a bunch of crap he had been watching on You-tube. Of course it didn't work.
But equally of course, this should not have been fatal.
3) The cop finally had enough of his crap and decided to arrest him. (Completely justified--tickets are really a simplified bail procedure. If you refuse to sign the ticket the cop is going to arrest you.)
Wait a minute; who gets bail for a warning? Since when has a police officer having 'had enough' warrant an arrest? Surely arrests are warranted by the actions of the suspect, not the police officer's temper? So not so much 'completely justified' as 'an unfair abuse of police authority due to the officer's bad attitude'.
4) Even then the kid was being totally stupid and resisted arrest. That's 6 months in the pokey.
But most certainly not the death penalty.
5) The cop attempted to tase him, it failed.
Demonstrating, if further demonstration were needed, that the cop was in no fit state to make any kind of judgement about anything.
6) The kid attacked the cop and was winning the fight. Now we're up to 2 years in jail.
Even if this unsubstantiated speculation were true, 2 years in jail is a long way short of the death penalty. We have no evidence that the kid attacked the cop - and indeed we know that the cop first attacked the kid (with a tazer), rendering any subsequent action by the kid 'self defense'. We have even less evidence that there was a fight that the kid was winning.
7) The cop finally resorted to his gun.
Seven times. So clearly the cool and calculated act of a rational officer of the law acting within his duty to use minimum necessary force. To end a conflict he himself needlessly started, and then needlessly escalated.
No. Of course not. Only a total idiot would suggest that he should.
Oh, look:
Definitely--we have a pattern of the kid making incredibly stupid choices and escalating the situation at each turn.
And of the cop doing the same. Oddly, only the less aggressive party is now deceased.
Should the cop bet his life that the kid won't decide to eliminate the only witness to his identity?
Yes. Because the probability of that is so small as to be no risk at all. Outside pulp fiction novels and film noir, ordinary kids who are stopped by the police for minor traffic infringements don't decide that their best course of action is to kill a police officer with their bare hands to 'eliminate the only witness'; even most psychopaths would re-consider such a bizarre choice of action.
