Does the Fourth Amendment prohibit a warrantless protective sweep of a home following the arrest of a resident outside his home under surveillance?

QUESTIONS PRESENTED I. Does the Fourth Amendment prohibit a warrantless protective sweep of the interior of a home following the arrest of a resident outside his home that had been under 24-hour surveillance for more than two months? II. Can the plain-view doctrine provide an exception to the warrant requirement when items are stored in opaque black trash bags that law enforcement officers observed while conducting a 30-minute protective sweep of the interior of a home after completing the arrest of the resident outside his home?
