Most Americans know that leftists never hesitate to use the power of the State to kill or imprison those who disagree with them.
Guns don't kill people. Criminals, the insane, and totalitarian governments do. (But I repeat myself.)
True, Guns do not kill people. Psychiatric medications that cause angry outbursts, loss of control over temper, and thoughts of suicide actually cause the killing of both innocent people and those using the medications.
Look to control weapons, (and automobiles, and aircraft) in the hands of people taking these psychiatric medications until a doctor certifies the danger is over.
