Congress should enact legislation that requires gun owners, gun sellers, gun buyers and those who are buying guns who want to use them to kill animals and/or human beings, for sport, or for whatever reason, to be required to take a psychological exam to see if they are fit to be around guns at all. There should be no exceptions. Involve the NRA in drafting this legislation. Involve whoever wants to be involved in the drafting of this legislation, but draft and pass the bill. I reference the Sand Creek Massacre, Columbine, Virginia Tech, Fort Hood, Aurora Theater, Tucson, Sandy Hook, Arapahoe, Santa Barbara, Seattle, Moncton, Las Vegas, Oregon, Charleston, Chatanooga, etc. as examples of how guns and mental health problems cause incomprehensible tragedies.
