Doesn't matter - he's ON PROBATION!!!! His butt, his blood and his urine belong to the state in exchange for proving that he can obey the laws of society . . . . . . . . which he obviously can't!
As do yours and mine, brother.
We just haven't been convicted yet.
Then the solution is simple... If you refuse to comply with the terms of the probation, probation is revoked, and you go to jail. Simple. End of story. But "the state" doesn't force a medical procedure like inserting a catheter, at least it shouldn't in the US. China, the old Soviet Union, sure... But not the US.
