Can someone please explain why we want to allow mentally ill citizens to be able to own and buy guns and ammunition? A pistol in our local high school last week - then this ... Seems that as responsible gun owners that should really be the foundation that we use to understand that kids, criminals, mentally ill, and addicts should not be in possession of guns. I grew up with an understanding of this - sorry it just baffles me.
Not attacking anyone here or looking to get attacked - if someone is taking medication for a condition such as schizophrenia - they do not need a gun - 
If you have a friend or family member that stops taking their medications for serious mental illnesses like schizophrenia - and you know they are in possession or frequently carry guns or knives please report the individual to the police for a potential interview. The problem is not that these are bad people - they have a serious disease and when it is left untreated - horrible decisions or actions may occur.
