“SCOTUS ruled, in Smith v. Maryland, 442 US 735 (1979), that individuals have no legitimate expectation of privacy regarding the telephone numbers they dial because they knowingly give that information to the telephone companies when they dial the number.”
I publish my home address. So, I guess I have given the government the right to a little look-see in my front window. But it’s ok if they are doing it to everybody.
This also violates the 5th amendment right against self-incrimination, even though I’m sure the black-robed cabal would argue that I didn’t invoke those rights with the proper words.
It all stinks, IMHO.
And if you don’t use the phone (much), that creates probable cause that you are criminal (otherwise, why would you make an effort to “hide”?), so any (federal) judge will grant a warrant.
