A few years ago, a fellow shot at a burglar fleeing his place of business. He missed and the shot went through a wall and killed a little girl across the street. It was very sad as I knew both the shooter and the girl's family. The shooter received a fairly stiff prison sentence.
This right here is why I would be perfectly fine with the pharmacist getting criminal charges brought up against him. Assuming he didn't hit the suspect he fired "at least five shots" towards him and could have shot anyone. If it had happened in his pharmacy I would be on his side, but the way I take this article is he chased him out into a public street and started firing.
