I wouldn't shoot someone running out of a store with a duffle bag full of clothes nor would I try to apprehend them because as you stated (maybe implied)...
They could be carrying a concealed weapon too. Not worth my life over inexpensive clothing, cheap electronics, or food at a store that should have its own security at the door.
In contrast, a shooting in a store, someone threatening a store employee with a weapon, or someone threatening me/family at a store is a different story.
Seeing someone steal from a store...I've seen that too many times since I was 10 years old including seeing a bank robbery in college at a nearby bank to campus, an armed gas station robbery in another country, a police shootout with gang members on the street while visiting an Italian friend, a bus bombing in another country, I was threatened with an assault weapon by a midget when I was a teenager, carjacking with an assault weapon at an airport in another country, car bombing by a crazy woman in another country that caught her boyfriend (a fellow soldier) cheating on her...
Two young ladies (maybe teenagers...they were young) running out of a Target would not merit my friend (a military officer) to pull out his weapon on them when they were running away...
Shoot them in the back near other innocent couples that had young children with them while those two ladies were running away from the store employees chasing them...hoping for a head shot with those big duffle bags hanging down on their backs ???
How would that look when he's days away from his military retirement !!!
By the way, my teenagers were with me too. We were traveling from another country (Quebec, Canada).
My point, you need to have the ability to quickly assess the situation you're in to determine if it merits using a weapon. That was not one of those situations...our involvement not needed nor requested.
Anyway, we bought lots of bags of potato chips from Target for the weekend barbeque/celebration for his retirement while on our way to visit another ex-military friend that was working as a manager at a nearby business.

Let me put it in a more simple manner. In recent months several stores in Durham have been looted by shoplifting gangs.
It would be simple for these gangs to simply drive up Highway 501 to rural Roxboro and loot the Walmart store. However these gangs know the retribution would be immediate and swift up in Roxboro. Walmart in rural areas is viewed not only as a store but a social center -- one of the foundations of the town. The population of Roxboro -- both white & black -- would not take kindly to their store being looted by shoplifters and most would take action immediately to stop the suspects. People can argue over the law and wisdom of stand-byers getting involved. But let me say that no grand jury in Roxboro would ever indict anyone who stopped (even with gunfire) a shoplifter who was part of an organized booster gang, and the law & order DA up there would never consider bringing charges against anyone except the shoplifter(s).
This is why booster gangs don't loot stores in rural & suburban areas -- while the booster gangs are happy to loot stores in a city like Durham where the progressive DA will not prosecute them and has a no-cash bail (catch & release) system.
