Actually, he has.
According to an incident report from 2015, Chow stated a woman walked into his store took cases of beer and another item, and then left the store without paying.
Chow then followed behind her and confronted her in the parking lot. That was then followed by a struggle over the groceries before the woman threatened to shoot Chow.
After the fight, the woman got into a car with an unidentified male. The two drove off and then returned to the gas station before
Chow fired six shots at the car.
In an incident from 2018, Chow claimed he watched a man come into the store take a $6 can of Easy-Off off the shelf and tuck it in his clothing. Chow then followed the man out of the store demanding for the item back.
Ultimately Chow was hit in the face by the man, before pulling his gun and firing two shots at him.
One bullet struck him in the leg.
Surveillance footage from an incident in 2013, that WIS reported on, shows two men stealing cases of beer from the gas station.
WIS reported then that the suspects ran out of the gas station while Chow chased behind them. The men then got into a vehicle waiting in the parking lot and Chow
fired three shots at the car as it drove away.
