Forget faulty speed cameras. Don't worry about police just guessing when they can't quite make out your license plate on a red light photo. Fear not the police who misread driving through a green light as running the red. Over in Ohio, apparently a court has said that police don't need any real evidence at all to charge you with speeding. They just need to make a "visual estimate" in their own judgment as to whether or not you were speeding:

In a 5-to-1 ruling, the court said an officer's "unaided visual estimation of a vehicle's speed" is strong enough to support a ticket and conviction. A radar speed detector, commonly used by patrolmen, is not needed, the court concluded.

"Independent verification of the vehicle's speed is not necessary to support a conviction for speeding," assuming the officer has been trained and certified by the Ohio Peace Officer Training Academy or similar organization, Justice Maureen O'Connor wrote for the court's majority.

That won't be abused at all...
