Where do you find federal supreme court protection for a right to privacy?

Do a search. Laws against birth control were overthrown circa 1965 on that
basis.

There are huge numbers of areas where the government goes
out of its way to violate privacy in order to enforce victimless crime
laws and very rarely is this reigned in on the grounds of privacy.....

I agree, and I'm sorry. Trouble is the only way any court can enforce its
decisions is to refuse to admit illegally obtained evidence. You would
think that once the SC ruled it unconstitutional to, say, beat confessions
out of people that cops and prosecutors would quit doing it but no - we have
a criminal government that refuses to obey the law. Police believe it
perfectly legitimate to violate your rights so long as they don't need your
"confession" to convict - ie if they can find enough other evidence based on
your "confession" or their illegal search they're home free.
