I went to a phillies' game tonite and saw two cops standing next to one another, both armed with revolvers. i'm surprised that a major metropolitan police force still issues revolvers, especially in a city like philly where violent crime is well out of control and cops are much more likely to have to discharge on the job, and maybe lots of rounds. is this common? the guns were of course holstered, so i couldn't quite make out what they were. i guessed .357 any body have a different guess?
