Problem with husband of friend - need advice please

[BretWeir]

Talk the the police. He might get questioned, but given the facts and the relatively skimpy hard evidence, there's almost no chance this guy is actually going to jail, and a 99% chance that no charges will be filed. But that's not the point; by at least making a complaint you:

1. Let the police know about the threat he made, which will make it much less likey that he'll follow up on it,

2. Put a scare into this douchebag that will hopefully make him have serious second thoughts about trying this kind of nonsense again. The cops are much more likely to get involved if they get another complaint against him, from his wife or somebody else, and it looks like a pattern of bad conduct.

It sucks that you have to be the person to get involved here, but it also sounds like this isn't going to be a very rewarding friendship in the future no matter what happens.
