Sorry, I can't follow your advice. According the the ARRL VE Manual:
VEs may not refuse service to anyone who is seeking an amateur license or upgrade, with the following exceptions:
• The applicant does not provide adequate identification document(s) to the VE Team;
• The applicant is disruptive during the examination;
• The applicant requires special assistance from the VE Team, such as accommodations for the handicapped that the team is not prepared to make available at that time. In such cases, the VE Team must suggest a convenient alternative date/time/location at which they will provide the requested assistance or accommodation (as required under FCC Rule 97.509). The VE Team should indicate in its public announcements that special testing assistance or needs must be arranged in advance.
• Service can be limited to a person when the VE Team has limited time available to it (such as where the test site must be vacated by a particular time). A VE Team might not be able or prepared to offer retests (where the VE Team has only come prepared to offer one test design per examination element).
We are VEs, not law enforcement officials. It's the FCC's job to screen candidates, including the examination of any terms set by a felon's release. Include a note with the test packet that you send to your VEC, if you want, but that's about the limit of what you can legally do.
