What I meant to write before I left for dinner but didn't have time to type:
In general, if somebody breaks into your home, you can still seek a remedy in court and get them penalized and your property put back - but that doesn't mean you can't also fight back during the commission of the crime. Defending your home against intruders is such an accepted defense against assault that the principle is only controversial when deadly force is involved. But if police officers are doing the breaking-and-entering, this ruling suddenly throws that defense out the window, even if they and the homeowner both know that they're breaking the law. Even if you know that for a fact, you're supposed to either depend on the court taking a defendant's word over police officers' on whatever probable cause/exigent circumstances they claim in order to provide an after-the-fact remedy, or end up convicted of what will doubtless be a felony assault charge.
