No disrespect meant Ekdog, my grandfather was also a cop, but unfortunately I didn't have the chance to know him well because he passed away when I was young. These abbreviations are internet fads, and I sometimes get carried away with using them (pre-mid-life-crisis!).

A bit of trivia... cop is also an abbreviation for Constable On Patrol!

Update on the gun issue: I received a call to pass by the local police station after New Years Eve so they can check-up on my alien residence permit. It seems that there's quite a few forged documents going around and the cop which took my statement wasn't familiar with these permits. Shame they don't let them do their jobs and bog them down with tons of bureaucratic BS.
