I have personally represented defendants that had probation and/or parole VIOLATED because they were charged with minor criminal law violations, or had NEGATIVE interactions with law enforcement, or failed to report such interactions.

Those individuals were eventually revoked (for the most part), and it has NOTHING to do with NOT being charged for any new crime.

The revocation was for their MISBEHAVIOR (or failure to report police interactions PROMPTLY to their PO).

I suggest you advise your loved one to ask for a revocation hearing and request a court appointed lawyer and NOT to explain or discuss the case in any form, shape, or amnner while he awaits adjudication.

Be advised, personal family matters (health issues, etc) have no sway on what the judge decides.
