There is a common denominator in all these mass school shootings and it isn’t the right to own inanimate objects. It’s the over use of prescription drugs specifically psychotropic drugs such as anti-depressants. Have any of these mass shooter’s not been on prescription meds? Americans alone consume over 80% of the world’s prescription pain killers. In Switzerland where there is a rifle in every home gun violence is virtually non-existent. More gun control will only result in more emboldened criminals and politicians. Freedom is not the source of our problems and as Benjamin Franklin said, those who trade freedom for security will deserve neither and lose both.
