BLACKSTONE, Va. (AP) _ Police officers took aim this week at vehicles and motorcycles zipping down a runway in Blackstone.
The tests are intended to convince judges that laser speed guns — increasingly popular among law enforcement — are as accurate as their radar cousins.
At least a dozen courts from New Jersey to Hawaii have taken what is referred to as judicial notice, or general acceptance, of laser speed guns. But some prosecutors and judges still aren't sold on the accuracy of the hand-held devices.
The officers — about 20 of them from Virginia, West Virginia, Maryland, North Carolina and South Carolina — hope their tests will change doubters' minds.
Laser guns have been used by officers to detect speed for nearly two decades.
