I guess this guy didn’t get that memo. Convenience store clerk shot during South Side robbery | KABB
One of the robbers stood at the door and told other customers inside the store to get out.
After getting some cash from the clerk, the second thief shot the clerk in the side.
Cooperating with criminals is not a guarantee of safety, it is a strategy for dealing with a violent confrontation. To my mind, it is not a very effective strategy. Violent criminals do not stop being violent based on any action you take or do not take. They remain violent criminals.
Better strategies are available.
