I believe that's a good consequence of the kind of universal principles that it would be nice to have for data but can't serve as one of those principles.

For example, Al Capone had some friends, and the government violated his right to socialize with them without being surveilled for good cause.

It's normal for rights to be taken away from criminals. Or do you mean pre-conviction... I think it's ok if it involves manual legwork.

Al Capone wasn't yet convicted of anything when they started wiretapping his phones.
