Unacceptable to have military grade weaponry available among the public. Especially when mental illness and drug addiction is so prevalent in our society. My right not to live among arms bearing, uncontrolled people is not being protected. We need sensible laws like those of Australia that control the sales of guns, and the banning of killing rapid fire weaponry. Wake up and do something to protect the innocent citizens of the USA. Ban this device that only enables more harm to be done.
