Holy cow, I stepped away for one day and now this is six pages deep.
I agree completely. The Bill of Rights concerns limitations on the actions of the government; it does not itself place limitations on the actions of specific people. Your First Amendment free speech analogy is spot on, and it applies to the other rights as well.
Those are indeed separate from crimes, which are covered by the US, State, or various other jurisdictional Codes of Laws. (The Constitution is the highest law in the land, not the only one.) If the government bugs your phone, that's a violation of your Fourth Amendment rights; if I do it, that's wiretapping, which is a felony in most states, and I'd probably do time for it. I also agree with what I take to be your next point, that our right to privacy does not give us carte blanche to commit any crime we like, as long as we have the door shut as we do it. Of course.
Everyone in this thread but me seems to be eager to relate this to Roe v Wade, the decision for which essentially stated that it is not the Supreme Court's job to state that a fetus is a person (with the associated right to survival) with such overwhelming surety that it overrides the other Constitutional rights involved, including the mother's right to privacy and right to make her own parenting decisions and so on, within parameters set by the States. Without making a personal statement on abortion one way or the other, I find it understandable how someone who can state without question that a fetus is a person as a matter of personal ethics, as you seem to be, can find this decision to be puzzling, if not abominable. I definitely get that.
The issue I objected to was the assertion that the Right to Privacy was "determined ... by SCOTUS" or a "bit [o]f fiction up until that point." It wasn't. It's been there the whole time.
