Provide a Well Trained Armed Security Guard for Every US School and Modify Some School Policies

The Federal Government should provide a well trained and armed security guard for every US school. It has been well demonstrated that criminals choose the least protected targets for their crimes. Let's make it so that our schools are their last choice! This idea would also create 100,000+ jobs very quickly. This guard should, instead of having just a simple sidearm, also shoulder an AR15 or similar high capacity defensive weapon in full uniform with a BP vest. Each school should be mandated to having only one entrance during school hours. All other doors are exit only and alarmed. This guard would man this entrance and patrol the school. There are about 100,000 schools in the US and paying an armed guard $30,000 would cost about $3 billion a year. I think America can stomach this cost!
