You are running from the truth as fast as you can -- that this particular cop acted badly and tragically.
Continuing to set up strawman arguments against a majority of conservative, CCL opinion on this thread that he is morally wrong (and as of the evidence known today regarded as 99% likely to be found legally wrong) does not help your cause; it hurts it. Getting him off on a technicality would not help your cause, either; it would reinforce existing negative sterotypes of guns, cops and STG.
Such extremely extreme defense of THIS PARTICULAR SHOOTING makes CCL, 2nd Amendment conservatives and FR look like they would rather back a flat-out murderer, only because he used a gun instead of a knife. Stop already.
Everything being claimed about this case was also claimed about Zimmerman.
I still haven't heard a good explanation of what the popcorn thrower was going to do next. Turning his back on someone he just attacked and sitting down seems totally irrational to me.
I'm sure that Trayvon Martin was surprised as hell to get shot dead. That was probably the furthest thing from his mind. He was just going to teach some "creepy ass cracker" a lesson.
My guess is that the popcorn thrower also didn't consider the possibility of being shot either and also was determined to teach a lesson.
What do you think was going to happen if no gun had been drawn?
