I have come across a very few cases--like maybe two--on the subject. Recently, say within the last year and a half.
I don't recall the details or even the case names. I only have a vague recollection of the outcomes. But, I'm pretty sure cops can warrantlessly search the inside of the house, even if they don't take the arrestee inside. Say, the cops arrest someone on the front porch. The rationale seems to be a protective sweep for other people who may be dangerous to the cops, for example, someone who may attack the police or try to liberate the arrestee. This sort of search would, I think, be limited to looking in places where a person could hide--closets, under beds, etc--but not inside dresser drawers and other places too small for a person to hide. Under the plain view doctrine, if the cop sees something illegal during his protective sweep, those items probably are admissable.
I also have the vague impression those cases were relatively low appeals court cases. Meaning, they might have been only state cases or federal circuit. I'm pretty darn sure they were not SCOTUS cases. If I'm right, this issue may still be undecided in any given jurisdiction.
