And what would you suggest "families and physicians" do?
This murderer, and yes, mentally ill individual is over age 21, who would you have "police" him?  Funding for that?  Have you recently driven or walked around Port Angeles and observed the extremely high numbers of mentally ill people that have been bused and dumped here? We have a TERRIBLE issue locally and nationally.  Did you not see that the family was trying to get the firearm taken away?  What would you have had his doctor do?  Go by his home daily to make sure he takes his meds?
