And no one on site with a concealed weapon to stop the shooter. I find it noteable that the police say they responded and were on-site in 5 minutes. That is a VERY LONG time. Five minutes. I suspect a shooter can fire 17- or more round magazine in 15 seconds, change magazines, repeat. That’s 34+ rounds per minute. Five minutes and that is 170 rounds. They could even stop after 2-3 minutes and leave, then be several minutes down the road before the police arrive. Bottom-line is police response is nice but no substitute for someone with a gun to defend themselves while they are still alive.
When seconds counts, the police are minutes away.
