Unreasonable search is always under attack though. There are many instances today of cops forcibly entering a home claiming nothing more than a welfare check, or "we received a call."
Edit to add that its also more difficult than it should be to protect and exercise the right against unreasonable search. If a cop knocks on your door its a consent-based interaction. You can simply not respond, but if you do happen to crack the door they can and will look in for any signs to claim as probable cause. Further there are cases where a person stepped out to talk and when they turned around and walked inside the cop slid right in behind them and later claimed in court the open door was implied consent. (I don't have a link to the court docs unfortunately.)
