eBay with aSavings has the Bushnell 101911 Velocity Speed Gun for $80 with free shipping. Features +/- 1.0 MPH accuracy, and can measure the speed of a baseball from up to 90 feet, or a moving vehicle from as far as 1,500 feet.
These are a blast to play with. Not sure how accurate they are, although when we used mine to get speed readings on some radio controlled aircraft it seemed reasonable. A fast Multiplex Funjet clocked in at 90mph in a dive...and yeah I was the guy holding the gun as my friend piloted the plane directly at me...good times.
I wonder if you can create havoc on an interstate watching speeders slam on their brakes.
Probably #1. Why not just get a police costume and some fake tickets and go in to the cash on the spot business?

#2 good luck finding any spots where the real cops aren't already in business.
