Do some people think you are paranoid because you sit facing the door at restaurants, scan the area in parking lots, check where the exits are in every where you go...etc?
If done right, no one will notice.
Let me give an example. Men like to look at girls, it human nature, so look at girls, Eye ball the cute waitress, follow her around the restaurant with your eyes, no one would notice, no one would think your paranoid.
That's just one example, Another, you mentioned parking lots. Look for your car, every one misplaces their car at malls 'n such. Look around, people are looking for where they parked all the time,
That's just two examples, there are millions more tricks used in surveillance that people never noticed. You just have to fit in.
I laugh when I see tacticool people walking around, trying not to be noticed while wearing black swat type pants with cargo pocketss, heavy laced up boots, camouflage, You know what I mean. Tell me they don't stand out.
Now how many of you pay attention to some middle age dude, Bermuda plaid shorts, stripped pull over shirt, mid calf socks with sandals?
Tacticool is fine for mall ninja types, but if you want to blend in, then blend in.
I really get a kick out of some of this stuff. How many times have you heard people on gun forums talking about gillie suits for LE Urban Counter Snipers.
Nothing says "blend in" like some one dressed as the swamp thing leaning over a patrol car with a rifle.
Sorry to get carried away, but I study people, now out of humor instead of having to.
