Seems like one of those, beg for forgiveness rather than ask for permission kind of things. It seems like most of the time the 4th amendment is defended through the exclusion of evidence found through illegal searches. Unless someone was going to get prosecuted for harboring a fugitive, there isn't going to be any wrongfully found evidence through these searches.
I don't know if Massachusetts has any kind of a castle doctrine, but it seems like the appropriate legal response to an officer barging into your home is blowing him straight to hell.
Of course no matter how lawful, there's no way any police force wouldn't just say "F*** your rights" at that point, and find a way to shoot you while you were reaching for a pen.
Hopefully, the offended parties of any kind of illegal searches will get some justice in the form of civil lawsuits.
