Why it matters

Brown, who has a criminal history spanning two decades — including trying to kill a cop — had “previously been diagnosed with post-traumatic stress disorder, anxiety, and depression,” Massachusetts State Police Trooper Christopher Hardy said in his report.

Common ground

The crack cocaine user expressed “suicidal intentions” before he unleashed a barrage of bullets while walking down Memorial Drive armed with an assault rifle, the documents said.

Perspective signals
