Anne, tgere us an effective method for preventing armed attacks, and it is.used by our government officiaks, eho regard their own lives as precioys. The White House, Congress and Supreme Court have armed security guards, metal detectors and x-ray machines. School boards have decided NOT to protect students and teachers because it costs money, they ate.immune from lawsuits, and politiciams want to use the massacres for their political goal of taking guns away from law abiding citizens. We shpuld enact a small excusentax.on furearms and.ammunition that is dedicated to funding the nachines fir any school disyrict that hires the guards to use them. Then the focus will be on the school boards who purpisely decide NOT to actively defend children.
