> Law enforcement is not necessarily the same thing as security

I'm having difficulty finding my source right now, but it appears that in cases of homicide by someone unknown to the victim, a police officer is the perpetrator in between 1 in 3 and 1 in 4 incidents. These statistics don't consider whether the killing is justified; they just observe that if people know of someone who was killed by a stranger, there's a 1-in-3 or 1-in-4 chance that stranger has a uniform.

And as we know, people's perceptions of safety are more important than actual statistics. We rewrote the nature of air travel in response to 9/11.
