Your fact pattern is unclear. If the home belonged to the parolee, then the parole officer had a right to enter it. If the parolee's brother attempted to prevent him from doing so, he probably violated the law and was arrested. He needs a criminal defense attorney. If the house belonged to the brother and not the parolee, then there does not appear to be any reason for the parole officer to want to enter. In that event, the brother needs to talk both to a criminal defense attorney (it sounds like he was arrested) and a personal injury attorney.
