He did expose himself to criminal liability. The sesible thing to do would be call the police tell them he thinks someone is trying to break in and he has a gun. Conceal himself and see what happens next.
Someone was trying to break into my house through the back door. I concealed myself under the dining table gun trained on the back door and waited. Too many dogs started barking, including my min pin, so he left without breaking in. I would have shot him where he stood.
