The Police
no they do not
No.
It depends on the particular state whether the police can serve an arrest warrant for a misdemeanor.
Yes they can search it
If they have a warrant, yes they can.
No they cannot come into your house with out a warrant unless the have probable cause.
If the police officers have a search warrant or an arrest warrant, then you have to open the door. If they have come to ask questions or for any other reason without a warrant, you do not legally have to open the door.
Not without a warrant or just cause.
Yes, there is no need for a warrant. The person can refuse to cooperate with the police if they so choose, in which case they might be taken into custody for interrogation at the police department.
Without a warrant you must find reasonable grounds to arrest someone, whereas with a warrant your reason to arrest the suspect already exists. Without a warrant a Police Officer can arrest anyone without permission of a Magistrate as long as they follow the correct procedures so their arrest is lawful, which is unlike an arrest with a warrant where you must be granted the warrant to be able to arrest that person. Without a warrant, a Police Officer can mess the arrest up and make it an unlawful arrest but with a warrant it is very unlikely that they make it an unlawful arrest.
