I dunno I scan pretty regularly and yes I look up. I have locked eyeballs with some more than scetchy folks and at that time I projected the “I am a predator.” disposition. That is actually a thought that runs through my head when I eyeball someone that appears to be “hunting” or “surveying” I have had some stand up straighter and flex and give me a chin up nod, I have had more commonly seen them drop their eyes and move off.
Little know often missed “Guy thing”
If I know you and catch your eyes guys nod DOWN
If I don’t know you and catch your eyes guys nod UP
The ones that worry me are the ones that never look up and are NOT on their phone.
Obviously there is quite a bit that can be observed for someone that is overly dressed or are wearing odd combinations moving with a purpose. Don’t get me wrong, flip flops, shorts a wife beater tee shirt wearing an open flannel shirt is a MK1 Mod0 Redneck with a gun. A guy with blue jeans, ball cap a t-shirt and an open Hawaiian shirt (Me) is a regular guy wearing a gun.
Pay attention to your Spidey Senses they are rarely wrong.
