I don't want to derail the whole topic, but there's a big difference there. Armed guards in schools are a good idea, while seatbelts on school buses are a bad idea. All research and testing shows that seatbelts would not materially change injury rates in bus crashes, and would actually increase injuries. Three or four feet of webbing with a buckle on the end makes a formidable weapon in the hands of a kid. Most crash injuries are minor, and rarely is ejection from a bus ever an issue-- which is the main function of seatbelts.
