during my four-year hitch in the Corps, a quick poll of the first-term enlisted jarheads in a USMC infantry battalion, asking "what are you going to do when you're hitch is up?" the most frequent answer would have been "become a cop"

and these were guys who, when off-duty, wore t-shirts with aphorisms like

"kill 'em all, let God sort 'em out"

and

"join the Marines, travel to exotic places, meet interesting people, and kill them"

i have a (completely untested) hypothesis, that police forces which require officers to be trained as EMTs and police officers (San Jose?) have far lower incidence of claims and proven instances of incidence of excessive force, abuse of authority, etc.
