Except he kept firing! Remember Stowers was already shot once and had called 911. I simply think that the marshall was not trained for average police street work.
What if's do not apply. Any common citizen whould be serving time.
I would agree that the marshall probably lacked the training in how to respond to such an encounter.
As I had mentioned in my previous post, it is common for officers to respond in such a manner.
A common citizen, one who is using common sense, wouldn't confront such an individual. They'd report this person to law enforcement. Nor would they be carrying a firearm in their vehicle. As you have stated, "What if's do not apply."
