I know most people don't want to hear it , but the only way to stop mass murders at schools is to make schools hardened targets. Even if all guns were removed from the equation, killers would still find a way to assault soft targets. I think the first line of defense for children to be safe in schools is to make sure that schools are a secure environment.
@Wolfman funny how no other countries have to do that
@ibid lol we didn't have to hunt or starve. My father was a Cherokee/Choctaw who lived through the great depression. During the depression they didn't have much money so feeding a family of eleven would have been difficult. Fortunately they were hunter/farmers with 180 acres to raise food on. Living off the land gave us something that most people don't have. Food Sovereignty.
