US Navy gunman was a Buddhist

Aaron Alexis seems a study in contradictions: a former Navy reservist, a Defence Department contractor, a convert to Buddhism who was taking an online course in aeronautics. But he also had a temper that led to run-ins with police over shootings.
While some neighbours and acquaintances described him as “nice,” his father once told detectives in Seattle that his son had anger management problems related to post-traumatic stress brought on by the terrorist attacks of September 11. He also complained about the Navy and being a victim of discrimination.
