Good for him!! I am sorry that he has to live through all of this, but at least he IS alive! Likely he would not be if he had allowed himself to be a victim, because at least one of those dirtbags would have shot him just for fun. That's how they operate, they kill just because they can.
I am sorry that he felt the need to close his shop and retreat from life, but I certainly understand his feelings and the reasons for his decision. I hope he lives a long, healthy, prosperous life.
A good lesson for those in our society who question the need for citizens to arm themselves against thugs like these. They reaped what they sowed...a life of violence and disregard for societies laws led to them not having a life at all.
