Parolees agree to let the police search them as a condition of parole. So no constitutional violation.
But they cannot force self incrimination.
This is not about him being a parolee, this is about this ruling being used in the future to self incriminate non-parolees.
You don’t see the pattern in how this really works yet? The seed is being planted.
Again... Today parolees tomorrow everyone universally.
Bet on it....
