Interesting story insane.kangaroo. I wish I could tell you that it was an isolated incident but it really wasn't. I can tell you that it is a rarity to be stopped and hassled though. I did some math on my own OC travels and out of the past 425 days I have only been stopped by cops about 5 times. Once thrown in cuffs, twice being drawn down on, three times having to put my hands on a car. 3 times were while i was in the street and twice was while in a private business. One time I was actually mugged by a cop and fortunately for him I realized he was one in time to stop my elbow from connecting full force into his throat...but I digress.
The point is that about 98.8% of the time I never have any trouble...the other time I get hassled I file a report, get an apology and in some cases get a department wide memo put out to illustrate the legality of OC'ing (I refer to the University of Pittsburgh PD).
All in all, come to Pittsburgh and continue to OC and eventually either the City will put word out to the Police Departments about the law OR you'll just meet every LEO who works for the city. I think we're heading in the right direction.
