It should have read:
Police say the pharmacist, identified as Dr. John Agyemang, distracted the suspect by telling him there was someone entering the store. While the suspect turned around, Dr. Agyemang drew his legally concealed handgun and shot the robber several times
That would have been my preference as well.
Fleeing, without anything that belongs to you and having not actually harmed anyone, generally speaking shooting at them is a no-no.
Being that the guy was a scumbag anyways, I hope the pharmacist gets cut some slack but I also hope he learns a valuable lesson as a result
