Why should CLEET be required? Since we already have a permit process, shouldn't that be enough and let the schools handle their own local policy?
I would say because having a SDA permit does not make one qualified to defend a school and it's population from an armed attack. If we are going to intentionally place an individual(s) in a school for the purposes of defense, they need to be properly trained.
Not that CLEET training makes one a hardened urban QCB expert either, but it's a damn sight more involved than an 8 hour SDA class.
