no becasue they can't even go inside a residence without a warrant
Yes. Depends upon the circumstances, for example, if the individual entered the residence to avoid apprehension and the police witnessed the act then they do not need a search warrant.
Yes
The police need a Search Warrant to enter a private residence in order to collect evidence unless they have reasonable cause.
Yes. The police can search any items if they have a warrant. It does not matter that no one is there to receive the warrant. The police only have to leave a copy of the warrant at the residence.
Yes, they can.
No, they have to have a warrant.
There is no consent needed from anybody when there is a valid search warrant in play. The court gives the police the right to search by granting the search warrant.
No, they need to verify that there is no one in the residence that is in need of assistance.
Sure, if that's what's printed on the warrant.
It depends on why he is entering. Was he called to the residence? Is he or she doing a 'welfare check'? What type of call history has there been at that residence? If the police officer has an arrest warrant, and knows the person named in the warrant is in the residence, then in the state of NC, the answer is yes.
If the police department secured the residence, and maintained security of the residence, they may search it however many times they like, within reason. However, as soon as the department relinquishes authority over the premise, the warrant has been served, thus a new entry would require a new warrant.
Under certain circumstances set forth in the law, yes, they may.
