I can see your point and it is quite reasonable.
However...that would make it very easy for the parolee to engage in criminal activity by hiding behind someone who cannot be searched. It is not unreasonable to say that those who agree to live with parolees have to live under similar restrictions.
Sanford (who shouldn’t still be governor, BTW) likely made the wisest decision here, but if he had signed the law, there wouldn’t be a violation of Constitutional principles as parole and probation are privileges.
No, that means that they will simply have to follow the constitution and get a warrant before they search.
