Another reason to my geekier male friends not to wear a trenchcoat year-round (besides the fact that it's just not a good look on you):
You are now in danger of being summarily executed by law enforcement. (Though I guess you're safer if you're a white guy. But still.)
Wasn't this a mechanic of the Shadowrun game for Sega Genesis? I do believe so. Trenchcoats or full suits of powered armor would make cops harrass you. So leave your powered armor at home, too. I don't care what night it is at Man Ray.
