Psychiatrist: Could these interventions have prevented the Woodlawn shootings?

This weekend, The Baltimore Sun reported a fire and deadly shooting in Woodlawn, Maryland. The fire was at the home of a 56-year-old man who for years claimed that the federal government surveilled him. He accused neighbors of being involved in this government surveillance. The neighbors recounted that he would sometimes march up and down the sidewalk with a gun or yell accusations from his porch through a bullhorn. On Saturday, authorities say the man attacked four people, killing three of them, before he was killed himself by Baltimore County Police officers.
