He used his own registered handguns? There's one for the books. Has anyone noticed that the common denominator in every one of occurrences like this,there were people close to the offender who knew they were dealing with serious mental health issues and said and did nothing? Pick any one of these incidents,anywhere,from Dawson College to Sandy Hook. It's really amazing that if someone had have said something,anything,to a family doctor or the local Police.these incidents may have been entirely preventable.
