Well this is very sad and very dangerous for you and your family . If this was done by a normal person they could be arrested and charged. But we are talking about a person who is suppose to protect soceity . If you have a cell I would record these threats and play them for some one you trust. Yes people say thing when they are mad but most people do not have a gun and is a police officer who can lie make thing disappear

Obviously said to instill a sense of fear.

If it were me i think I'd push the 'treating those you love with respect' aspect rather than bow to threat and intimidation

Record him and report him

That’s straight up crazy and criminal -
