People have long existed due to their innate ability to recognize patterns. Look at Fed and state stats to determine just who/whom your likely attacker might be, given proximity to a known dangerous zone. Who hangs around there, in numbers? What do they look like. This - is not realistic nor helpful - "Stop trying to identify bad guys. That’s not your job. Identify developing problems instead." Oh yes it is by quite a long shot. You will not be attacked by an Amish grandmother out for shopping. Most of us can and do see just who the problem might be, while gassing/charging our vehicles or retrieving them from a parkade.
