Check out this firefighter tattoo website that is incredible. www.strikethebox.com It has everything you can imagine sorted into seperate categories. Set some time aside for browsing. You'll need it.
Unfortunatly I did not find anything remotely similar for Law Enforcement. Just a few here and there. This one above was under "patriotic" on a regular gallery. I know there are plenty of cops getting work related tattoos. I've even seen a few of them. So I ask, what's up with that? (Are you really going to let the firefighters show you up?) Someone, build a police site so I can link it!!!!! (and browse of course)
