I knew two men with depression (possibly other conditions, too). Both were alcoholics, with long term sobriety, but went back to drinking.
Both committed suicide. One quietly, the other in a big showdown. The big showdown guy wore red-white-blue, professed to be a big patriot, held his family hostage inside their townhome, released them, and then stepped outside the apartment.
The officers told him to put his rifle down, but he raised it to point at them. They shot him. He died. He was my friend. I knew him from meetings, then saw a picture of him posted on FR from a patriot type rally in our area.
Very, very sad. He used to bring his daughters to AA meetings, so people got to know him and them.
