TigerEye,

By some respected estimates, one in six American women will be the victim of outright sexual assault (excluding statutory rape) at least once in her lifetime.  Would you venture to guess how many of these now living victims and potential victims had, or will have, a police officer at her side during an attack?  I'm not at all declaring the deterrence value of organized police forces is zero or non-existant, but I will say that the wry phrase "when seconds count, the police are only minutes away" is grounded in a fundamental truth, that an individual's personal safety and protection depends foremost upon herself (or himself, as may be). 

That said, I agree that an armed bodyguard, or better yet, a dedicated armed security detail would be nice when hopping about town or during a sojourn in a place where I don't speak the language - but a Hillary Clinton I am most assuredly not.
