Can You Get Out Of A Traffic Ticket Simply By Asking To See The Radar Gun?

Easton Corbin was recently pulled over for doing 85 to 87mph in a construction zone, which traffic fines double in, and ended up paying a fine over $1,000.

This brought up a question from Gunner that if you ask the officer to see the radar gun to verify how fast you were going that he has to show you and if it doesn't show your speed then can get out of the ticket.

I've never heard this before and don't see how you could get out of a ticket simply by asking to see the radar gun.

Is this true?
