There’s not enough information in this snippet to draw conclusions. I didn’t read that Bill Cosby was advocating gun control.
It’s possible that the situation may have ended better if Zimmerman didn’t feel empowered by his gun and had called for backup. Any good ccw instructor will tell you to avoid dangerous situations, even (or especially) when carrying. Perhaps Zimmerman wasn’t trained properly.
However, I do wonder if Mr. Cosby’s personal security is armed.
Mr. Cosby was at a convenience store frequented by my husband about a year ago. Hubby recognized him right away, but didn’t say anything. Hubby then went outside and was headed across the street when Mr. Cosby started talking to him about basketball. He was alone. He was on his way to a March Madness game all by himself. He looked like a nobody. I doubt he carried a weapon since he was headed to a weapons free zone. Hubby says no one else even recognized him.
