It would be ironic if the police officer was still mourning the death of Deputy Cole and decided not to confront a crazy person he didn't know. If someone is determined to kill themselves by doing something a normal thinking person wouldn't do, why would the responsibility lie with anyone other than the person making irrational decisions?

Your brother was a free person, able to make his own decisions. We don't live in a police state up here in Maine. People are allowed to.make mistakes and pay for them. The onus is not on anyone other than himself.

I'm sorry your brother came back from the war a changed person. That happens. It's one of the hortors and evils of war.
