It is a false narrative to blame the NRA, not one of my  favored organizations, for mental health issues.    Wouda, coulda, shuda always come after the fact and is easy to use when we truly do not know everything that was or was not known.  Sure I wish this person had been prevented from killing those five individuals in Florida.  But I truly believe that a person in his mental state will find many ways to follow the guiding voices in their head.  

We want laws and agencies to protect us from the crazies. Yet we also expect the crazies to not be unduly restrained from their rights.
