I deal with a lot of law enforcement personnel in the hospital, and while most are very decent, every now and then, I run across one that scares me more than the inmate patients. So I guess if I were asked out by a cop, I would have to tread very carefully.
Also, I am sure you know that cops have a higher than average divorce rate and lots have issues with ETOH. Objectively speaking, that is reason enough to be cautious.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
