"warranted" Is this meaning they Have a warrant? If so, there is nothing you can do except demand to see it. It cannot have any changed not in ink nor not initialled and dated by a judge..
If they Say they have" probable cause or reasonable suspicion", say NO. Lock car doors.
If it is a 911 call, cops can enter without warrant and check immediate rooms. Not search house. Same if they hear shots from inside house, screaming, smoke, water coming out.
