Generally when a shooter is confronted by another person with a gun they either give up or kill themselves. Cowardly act just like the act of shooting unarmed people. They go after soft target rich environments. Which are schools and places guns aren’t allowed. There is for sure a mental problem. The Columbine killers were all on a psychotropic drug. Would like to know how many of the other shooters were taking these type of drugs.
