He sounds like a nice person. It may be that he didn't shoot anyone.

Can the police really know the truth with 100% certainty within one day? Even if they do, should they be pronouncing judgment before your neighbor has the chance to defend himself?

For example, suppose A shoots B. B is A's brother-in-law. A has to get treatment, has to tell the cops something. He doesn't want to finger his B-i-l, because B-i-l has eight kids which A will have to help with. So A fingers your neighbor, whom he doesn't like.

Stranger things have happened.
