Another Homicidal Maniac allowed to run loose

Flips out and kills six, seven, eight, or more college students in Oregon.  Before the bodies are cold, Obama is on TV bleating for gun control. 
  How about some nut case control?  Someone should have noticed that something wasn't right before he started killing.  Parents, teachers, relatives, friends, co workers, someone.  Some psychiatrists should have examined him, diagnosed him as a homicidal maniac, and committed him to a mental hospital. 
   Well that didn't happen.  Apparently it never does.  If someone else had been carrying, they might has stopped him.  Wanna bet the college forbade carrying on campus?
