I don't think arming teachers is a great idea. I'd bet that more harm than good comes from that. Where is the gun stored? How often does the armed teacher have to attend shooting practices? I do like the idea of an armed LEO at each school. That helped in the Maryland shooting. Would have helped at Parkland had the officer actually done his job.
I’ll address this as well.
Your concerns are valid. I don’t believe more harm than good would come of it. The idea behind teachers behind armed is kind of a backup should the LEO fail as in Parkland.
As far as storage the gun the teacher should have access to it at all times. So if the teacher leaves the classroom. The teacher secures it somewhere on him or her.
Teachers should have to qualify their ability to shoot annually before the school year starts. The teacher can practice on their own dime, but would be able to write this off on their taxes or receive a tax credit for up to a certain amount.
I would go a step further and ask for volunteers to put teachers through a shooting stress test. A school district could ask for veteran volunteers to put teachers through it. Personally, I would require that the stress test be administered by veterans who had a combat MOS. If the city of Cedar Rapids asked me, I would do it for free.
If this were implemented, what kind of decrease in school shootings would you need to see for you to deem it a success?
