Was going gun the answer here?
Here is a video..
My opinion: No.
With the little girl literally in the line of fire, it makes no sense to start the festivities. In fact, I think it is downright irresponsible. The shooter had a chance to move and use the pump as cover, it also means he could have retreated safely and let the bad guys take whatever they wanted but instead he muzzled the girl at least twice, maybe three times.
On the info accompanying the video, it says it was an off duty cop with his daughter. It makes more sense to me to snatch the girl and run away.
Stupid saved by sheer luck.
