Guy, our problem is not the guy who can afford a home machine shop or a 3-D printer.
Our problem is the street punk who buys from one of Whiner-borns heroes who absolutely insists his straw buyer passed a background check. OUr problem is the disturbed kid who takes mommy's gun to school and settles his bullying problem.
Our problem is 32,000 gun deaths and 78,000 gun injuries every year.
