Waiting for an oil change on my wife's car I picked up a magazine titled ABRN Auto Body Repair Network, dated September 2017 about preparing for an active shooter.
The Article didn't have a lot of insight it mainly referenced ALICE training. I can't see an auto body shop being able to facilitte some of the recommendations.
