Ohio has front tags. It's the law to display them or it seems they wouldn't go through the trouble and expense of issuing front and rear tags. To pull someone over for not having one is no different than an Indiana LEO pulling over a car for no tag on the back bumper. From what I understand this leads to finding felons in possession of controlled substances which leads to arrests. This prosecutor seems to have gone to the Nifong (Duke Lacrosse) school with the murder charges. Bad situation, not murder. The stop seems legit.
