No he isn't. Some people are better suited to these situations than others, and people can be better trained for it too. I've talked to more than one Iraq veteran who's troubled by how ready police are to discharge compared to the rules of engagement they used in Iraq, which were more than sufficient for them to maintain public safety.

Part of the problem is that police in America offer the default excuse of fearing for their lives in virtually every situation where they shoot someone. I doubt they're actually that cowardly, but it's been a successful formula for them in administrative proceedings.
