The mass murder thing isn’t an Obama problem. It’s a mental health problem. Compare the percentage chance of a gun owner committing this type of crime, with the percentage chance for of somebody on this class of medication committing a mass killing. The difference in the probabilities will be striking.
It’s actually a spiritual problem. The libs and atheists have successfully removed the 10 Commandments from schools, court houses, etc. So, Thou shall not kill,” is foreign to most.
