I suggest you go read the 4th ammendment again:
Fourth Amendment - Search and Seizure
Amendment Text | Annotations
“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”
You have completely glossed over the instructions that follow ‘unreasonable search and seizure’.
PROBABLE cause..supported by OATH , describing the place to be searched, the persons and things to be seized.
You are really dug in here and I fear that you will see no reason. If these types of searches went on as a matter of course all over Watertowne and Cambridge..and no one objected..then their liberal indoctrination is now complete. I have seen no proof as of yet though that this was what went on at most homes.
It's only common sense.
Do you think law enforcement should have gone to get warrants before they entered every office space in downtown Manhattan on 9-11-2001?
