But schoolhouse shootings are not being done by infants and toddlers. They are being done by people old enough to figure out any lock that an adult can figure out. Child-locks provide no protection whatever against the premeditated murder of school children and their teachers. Moreover, most guns already have safety devices. Maybe some parents are not responsible enough or thoughtful enough to remember to take the bullets out of guns that they keep in their homes.
Many people keep guns in their homes to protect themselves and their families.
Studies show that these guns have in fact saved great numbers of people from being victims of intruders in their homes. Multiple safety devices slow down the very people who need to be able to fire in self-defense. Criminals with guns will undoubtedly already have them unlocked and loaded. Zealots for gun-control laws never seem to understand that criminals do not obey laws. Gun control means unilateral disarmament of law-abiding citizens.
