For schools, I like Sheriff Joe's idea of using the posse to staff armed volunteers in every school. The feds can kick in funds, but the sheriffs manage their folks. I would make available bullet proof vests and ccw training available to teachers and staff at their option. At a minimum, teachers and staff would be trained and required to carry tasers.

For other gun free zones, I would mandate armed guards to protected the unarmed populace. Additionally, I would consider fining media for excessive coverage of mass shooting, so as not to encourage others. Non compliance means they would lose their broadcasting privileges or have their printing presses and web sites shut down. For the excessive law suits I would limit lawyers to 5% of the verdict, because Im tired of hearing about the huge lawsuits where the lawyers win big.
