Yeah, it's a shame his neighbors' sense of community or his family's involvement in his life did not run to actively trying to get him help.  Kind of a shame we live in a nation where retired Americans can wind up in financial distress and lose their homes, which was backstory to all this for Musser.  But once Musser is shooting at people, he's created a situation where public safety has to be protected.  And even then APD bent over backwards to peacefully end the situation -- not like this was a no-knock SWAT raid, it went on for days and ended when he escalated it back to gunfire.
