there are rising calls for School Resource Officers in ALL schools, all grades. i don't understand glass windows in locked doors either. make it harder to get in & give LEO (whether SRO or outside) time to respond. here is a situation where you actually NEED former military as LEO, already trained to run towards the sound of gunfire...in a (nearly) perfect world, THEIR guns would be the only ones heard.lets hope the cops responding act like those who responded to the Nashville school shooting.
