Yes... I assume they had a reason to be there.

THey don't NEED a warrant for you to produce an ID.

THis has what to do with Small Claims court questions?

Why were the Police in your home and I agree with Smoothy - how is this related to Small Claims Court?

They can ask you if you are a Braves fan if they want to, and of course if there is a issue or question about who you are, they can ask for an ID.

This issue here is why are they in your house, since they can not come in your home unless they have a warrant, or you allow them in.

In most areas ( but not all, you did not say were you were at) they are allowed to ask you who you are, and in most can ask for ID, you are not required to give them an ID in many places, ( unless driving) but have to tell them who you are.

So a lot more details are needed
