How easily can people get access to bombs? How easily can they purchase poisons or biological weapons? How many school children have been murdered in their classrooms by bombs or poisons?

The problem is the absolute ease that people in the US can get weapons of war to carry out their ill intent against innocent school children.

Nearly half of US parents are worried about their children getting shot Source... how many people in the US are truly worried about the government murdering them versus a random lone gunman with a high-powered weapon?

I understand your concern, really I do, the US government has never proven itself to be trustworthy... but my question to you is what percentage of school children would it take to be affected by gun violence before you'd change your mind on gun regulations?
