Watch this video: police at the house

People have to comply with orders from police officers. The citizen does not always have the same information that the officer has. You may be arrested based on false information given to the officer, but the officer has no way to know if the information is false. If the police had to ask permission to arrest someone then very few people would be arrested. If you are innocent you need to fight that in court.

BTW being innocent is not a legal defense to "resisting arrest".
