The first paragraph is an attempt to illustrate another's opinion, not mine. My opinion is murder is murder regardless of who died and who caused it. 

The video you posted is a great example of what I was talking about. I can see both sides of the argument there. I can understand the reasoning for the high alert going in, the suspect is armed. I believe in most situations it is illegal for an officer to fire without making their presence known first.
