Three contacts.
First one was before CCW in NE, had gun on front seat, legally, with Omaha open carry permit on 52nd street about Saddlecreek. Long story short, in handcuffs for 25 or 30 minutes, a long-winded talking to about my not needing to have a gun and what the hell was I doing with one... He gave it back, but had me unload it and put it in my truck before being so kind as to release me. I ended up with officer M. Camp**** and his Sgt. calling me and apologizing after I lodged a formal complaint. I did enjoy letting him know the difference between the 1930's Germany and our country...
The second was by another Omaha cop, and the third a sheriffs deputy. A speeding ticket and a license plate tag expiration, respectively, both simply asked where the gun was (after divulging my CCW status) and then they each basically said "OK, thanks for telling me" and that was it.
M. Camp**** was a young cop, likely fresh from training and very, very unsure of himself in regard to the laws of the time, about 6 years ago. I'm sure that today he's a fine LEO now that he has some experience and has been better educated. Officer Camp****, "you're welcome".
