whether he deserved to die and whether his shooting was justifiable are two different things.
No he didnt deserve to die
was his shooting justifiable by the police officer yes it was.
thats what makes it truely unfortunate, the majority of cops would do the same thing I would think if you think your partner is having a gun pointed at him youre going to nuetralize that threat just like the one officer did was it a mistake of course did the suspect play a huge role in his death yes he certainly did.
Finally we are in agreement. The cop made a mistake. A HUGE one that cost an innocent man his life.
The only saving grace to be found in that video is the fact that the one officer ducked.
However, he was not the one who opened fire. Too much adrenaline clouds the judgement.
I'm not arguing this guy was singled out for abuse, ...simply that this was one guy who police didn't fail to stop.

Personally, I would've preferred they send him a summons in the mail, that's far more preferable than this outcome.
As an aside though, it would be interesting to conduct a social experient where people got to be a cop for a day.
Not a real cop who goes out on patrol, ...just one who dons the uniform and utility belt. I think it would be quite revealing to see the immediate transformation that occurs. As a cop, I'd be embarrassed as heck to witness that, and to understand society's true perception of cops, as they mimick them in every way.
