Mental Capacity

One Addendum on my thoughts about gun control, The mental capacity of a person should be considered for the purchase of any firearm. It is now known that the VT shooter was admitted to a mental health facility in 2005. This should have been taken into consideration and he should not have been allowed to legally purchase a firearm. This of course would not have stopped him from getting one, and these tragic events most likely would have still played out. Their needs to be a way to check the mental background of individuals before purchase. I'm not sure how this can be done but it should be considered.
