@Tropical_Willie They would need a warrant to actually go in the home and search. Or, they could get permission to search the home (which can be revoked at anytime, so they’d just go for the warrant).
Breaking up a party doesn’t mean they have to enter the home. They can’t just enter a home like that anyways without permission.
If you are having a gathering illegally, they will knock on the door and tell you that you need to break it up. They can’t just enter the home unless you say they can (or warrant), and they wouldn’t even be able to get a warrant unless there was some other reason like drugs or something. A party isn’t enough unless they have something else too
