"Active shooter" is not at all the circumstance here.  An "active shooter" is someone who is an open threat to the public. We've had far too many of them, but Mr. Babb was NOT one of them.  Additionally, "on drugs" is used by you as part of the justification.  Mr. Babb was taking perscriptive medications to address his physical and psychological issues, he was not an Illegal Drug User as your comment implies.
