> There is an array of causes from physical illnesses, mental illnesses, spiritual beliefs, political beliefs, to even cultural beliefs. Sure, loneliness can contribute in some cases

Sorry, I was unclear. I meant that loneliness is often a major proximate cause of suicide. An interruption–even something as jarring as the cops at the door–can snap someone out of a pattern which, if left alone, can end in tragedy.

A mental-health professional, or friend or family member, checking in would be ideal. But that isn't always possible. In the absence of better options, a cop checking in is better than nothing.

What does loneliness have to do with being physically close to a person? Lonely people walk among other people all the time.

Someone asking if they would like a receipt, and “have a good day”, ought to snap someone out of it just the same with this logic.
