Many men are very good at self-preservation. They pack heat, they have years of fighting training. Quick eye, good senses, decent stack of money, nice car, they got their game together.
Then they get naked with a girl and it all goes out the window. Leave the glock in the truck. Drink 5 shots in an hour and get tore up. Sleep in a place they've never been with a girl they barely know.
This is the chink in their armor... the economy is down and there is NO easier way to rob a dude than to get him drunk, naked and vulnerable. I don't trust the dude on the street I see approaching, but I worry more about the dude in a closet ready to beat my naked ass with a bat.
