" I believe in a citizen's right to have firearms. "
I disagree if it's a bat-shit crazy citizen who has been diagnosed as mentally incompetent to possess a firearm. There NEEDS to be some laws put into effect through legislation that people with serious mental instability who have been diagnosed as such by doctors and it's been documented and recorded , i.e. schizophrenia, bi-polar, manic depressive -especially those with a violent past and it's been documented should NOT receive firearms. Period. And have these records accessible to gun dealers through computers in their respective stores.
Of course I realize this won't stop criminals from getting guns through back door methods but it will restrict somewhat how many nutcases purchase firearms through legitimate firearms dealers if there were a " mental stability " check available
