The predictor is already there when you are "approached" for doing nothing wrong or even suspicious. Have never had an officer come up to me and say, " That sure is a nice way to legally carry a gun without a permit. Be safe now, ya hear."
I have had LEOs take notice, nod and smile, and continue on with what they were doing.
I have had some do the same, our state troopers have had an excellent reputation for doing so (at least with me) and I even started a thread about that.
I am not necessarily talking just about OC though. I've tried filing complaints and treated horribly in doing so, was approached by deputies at Starbucks, who demanded ID, I thought it was about OC turned out later it wasn't, and they were very to put it politely "irritated" and instantly labeled me as uncooperative and belligerent even though I re-iterated several times I am not trying to be uncooperative I just don't want to inadvertently give up rights.
A few weeks ago, was called by a sheriff about my car in a ditch, I was at home getting a tow truck to get it out, he asked if I wanted to tell him what happened, I told him no offense but due to bad police encounter and advise from a lawyer I don't feel comfortable doing so. Well in started the threats of arrest and accusations of me again being "uncooperative".
These are just two examples of the many encounters I seem to have. My situation were I received a settlement from the city of Bellingham, brought about because of OC was even worse. Threatened with continual harassment. Which sadly seems to be the case. Recently officer Bass of BPD, looked me up (he knew who I was) lied to the DOL for the reason of doing so. Called me on my private cell phone to "discuss" the matter.
So in my experience they absolutely do not like their "authority" questioned, no matter how polite you do so.
