A question for my law enforcement friends. And a story to tell. Sorry if it's a little long. A near neighbor came over yesterday and told me he had a visit from the police. I wasn't home and missed the whole thing. He was at home alone when there was a very loud knock at his door. He was in his underwear so he looked out his window. Two city cops were in his front yard with their guns drawn. They did not identify themselves as police when they knocked. And they started yelling for him to come outside. He told them he wasn't wearing pants and he would be there in a minute. They demanded he come out right now. He said he went to the bedroom and put his pants on then went outside with his hands up. It turns out that they were attempting to serve a warrant for a class 3 felony on his adult (about 30 yrs old) son. He explained to the officers that it was his son and he hadn't lived with him for some time. At this point they asked him for ID. He refused saying he obviously wasn't who they were looking for and he had no idea where the young man lived. At this point the officer threatened to arrest him if he didn't show his ID. So the question is does the law require him to show ID. We talked about this at length. The house is in his name and as he says it's not his fault the information they have is old. Anyone could find out who he is. Home ownership is a matter of public record. The name on the warrant had no real connection to the suspect. Could he have been arrested?
