As much as I feel for the cop and his family, I think it would be wise to consider Civil Rights here. Can anybody here, or the police, for that matter, say that he was guilty beyond a reasonable doubt for the crime of killing a police officer? Yes, it's more than likely that this 'dirt bag' did it, but I would rather the courts make the final decision, and not a volley of bullets. Police are not judge and jury in this land, and they shouldn't be. They certainly shouldn't be fullfilling the role of executioner.
No, I feel nothing for the guy the cops killed. 1 bullet or a thousand. If he threatened them, thus causing them to fire first, then so be it, but if this was a retributivist execution, then it is wrong, plain and simple. Go ahead and tell me that I am igonorant, myopic and disjointed from reality. Go ahead and say 'you've never been a cop before', or 'you've never lost a good buddy'...I've also never been dragged out of my car and beaten or shot by police because of a suspicion of guilt, and I'd like to keep it that way.
The fact stands that in the US, you're supposed to be innocent until a court proves you otherwise. It is a good and decent value that protects us from our own government, and nobody, much less a worthless cop-killer, should be used to justify the violation of this value. NOBODY.
If every cop acted on his anger, wielded his deadly force based on his adrenal gland and not his brain and his training, then this nation would consume itself from the inside. Cops are enforcers of the laws, and keepers of the peace, not vigilantes. Small community or large, it makes no difference. What's next? Blowing a guy away for failure to stop? I don't want to be a prisoner of the law enforcement community. I doubt anyone here would either.
