"Are you saying the police do not have a right to put a criminal suspect under surveillance at his home?"
That is correct unless the police have good cause to believe the person has committed a crime that warrants taking away the right to privacy.
This usually takes a court order but that can be waived in time sensitive emergencies.
"Amendment IV - Search and seizure. Ratified 12/15/1791.
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."
They can sit outside his house, though.
