Should it be illegal? License plates are in public view, so it seems they&#x27;re meant to identify the vehicle for whomever sees them.<p>If people have the right to record that number when reporting a crime (which they sometimes do) then surely the government has the right to keep track of it as well. That is presumably why they issue the plates and require them to be visible to begin with.<p>It seems unreasonable to allow the existence of license plates and then complain when they&#x27;re being used for their intended purpose.
