Yes. In my mind, one of the biggest concerns is that these kids, so often, keep getting the guns on campus without issue or incident, it seems.
I am glad my kids’ school has a clear backpack/clear lunchbox policy, but I really do not think anyone is immune from these sorts of tragedies. Though the backpacks are clear, and this is supposed to be a deterrent, nobody actually looks at/through my boys’ bags.
It could still be relatively easy, IMO, for a student to conceal a handgun or other weapon (e.g. weapon wrapped up in a hoodie or sweatshirt w/in the clear bag). All MOO.
