Doesn’t matter. If he refused, he was within his right. It is his home. The police caused the problem, not the man.
No, I’m sorry, that is not the law.
Please see #99.
P.S., don’t feel bad. People are often mistaken about that Constitutional principle.
By the way, under current Constitutional law, if a woman called 911 and reported that she was being raped and held against her will, and LEOs felt she could be further harmed, she would not even need to give (or know) a specific address for LEOs to execute a warrant-less search.
If their called ID indicated a specific address of the calling telephone, that’s enough.
