CCW is not going to help in this situation.
You shoot one of these dudes with a handgun you are going down, hard. You will be arrested, tried, convicted, and sent away for a long,. long time.
When the shooting starts, it will be from a long way away, done by people who can make a thousand yard shot and be gone before anybody knows that there WAS a shot.
yes
or perhaps 750 yards from multiple directions
.....bingo.
