Sound off!

People speeding in Missouri are about to have a sound cannon blast through their windshield.. (not an ONION article) .. 

The Missouri Department of Transportation is unveiling two LRAD sound cannons which will reportedly start by targeting those who speed in construction zones. 

 KMBC NEWS says it’s an ‘attention gabbing way’ to get drivers to slow down (and maybe scare the hell out of a few who think an alien will be landing on roof of the car..)
