Nobody is perfect, maybe the police just got the wrong address. As soon as you realize it is the police and not a crook I would not interfere in any way. These guys aren't going to bust in without a warrant and their primary worry is probably making their wife a widow.
In today's world you have an endless menu of rights if the entry was illegal. You can sue them into penury, but let the police do what they think is their job. I would not interefere. Most cops I know are good guys just doing their job. You aren't defending America or the Constitution by resisting. America is a free country with elected public officials, if you have been wronged you can sue them in a court of law and have the matter decided upon by a jury of your peers.
