I went through and redrafted the incident after I posted here, to go into further detail about some of the positive interactions I had before the single negative one.
All told I've got 9 pages handwritten on a legal pad, and a couple of hand-drawn "maps" detailing my route and approximate times (times beforehand are shady, cuz I didn't know I'd need them) that everything happened.
I'm gonna contact a lawyer just so my complaint goes farther than "Well, yes sir, we understand you're upset, and we'll be sure to do something about it" and into the shred bin once I turn my back.
The detective was professional enough once he got there, but I'm still upset that I was treated like a criminal with the "escort" through the mall, especially since he made me walk a step ahead of him... embarrassing.
My lawyer is a personal friend of mine (my old college roommate, and a regular golf buddy) who's gun-friendly and will most likely take care of this if I buy the beers next time we go out... I called him and he told me to draw up the "informal" report that I have sitting here and we'd talk about it Monday.
Evidently SCMPD has somewhat of a reputation about being hard on gun owners. I don't quite understand how, with the large military presence in Savannah from Hunter AAF and from Ft. Stewart (25 miles away) but I've heard informally that this isn't the first time something similar has happened.
