They often give a clue. like about 20 years ago on a beautiful Sunday around noon when I pulled up to an outside ATM at my bank (I had a CCW and a Colt Pocket Ponylite .380 in my front pocket and a Glock 30 over in my car).
A car in the adjacent gas station sped out.
First clue:
The car went down the wrong lade of the divided road to pull into the bank parking lot.
Second clue:
The car pulled into the handicapped spot right behind me.
Third clue:
There were five hispanic youts all wearing the same red pattern bandannas over their faces.
Fourth clue:
I could hear them ad they were arguing about who was going to get me. “You gettim”, “no you gettim”.
I was done with my transaction and grabbed card and cash and sprinted to my car and Glock 30 that would be more suitable in a 5 against 1 fight.
But, thy were already burning rubber out of the parking lot. It happened so fast I did not get their license plate number. It was probably stolen anyway.
