There is nothing unconstitutional if given as a choice. We have no trouble with taking the vote from felons even though the vote is a constitutional matter. He has the choice of a full throttle probation period, within the sentencing guidelines, or a lesser probation if he gets an arm stick. If he disagrees with the vax he can take the longer probation. Frankly probation is no big deal. A pain, but no big deal.
