The way around some of the provable issues is to prove the harm and loss of family members of registrants… the children and spouse. How are states victimizing a portion of the public to protect another segment of the public? Public Safety? Who is the public? They are not protecting my family members, so it is not public safety but it is selective safety. The irony of all of this is how ludicrous that any reasonable person decrees that the registration is not punitive. Anything I’m required to do physically that has a punishment of imprisonment IS PUNISHMENT. DMV every 4 years requires physical attendance if I want a renewed license. But I’m not imprisoned if I choose not to go; I simply don’t get a license to operate a vehicle. The level of absurdity of our legislators is astounding.
