A defendant had drugs seized from his townhome without a warrant. The seizure is upheld in court. What might explain why this warrantless seizure was upheld? (A) An officer saw the drugs while walking up to the home on other grounds. (B) An officer noticed a guest entering the home and thus had probable cause. (C) Townhomes are not given the same level of constitutional protection as other types of homes. (D) The drugs were in trash bags in the front yard and thus not subject to the warrant requirement.
