That Guy
I hate to be the thorn in the side of your enthusiastic bubble, but my guess is that you can put your creative mind to some better use of its resources... In this case, you're spinning your wheels... Figuratively, that is...
How do you know if it was the front facing Radar antenna that was active at the time this reading was obtained? What if that officer had had his rear facing antenna set to measuring speeds?
And speaking of cosine effect, if you've looked at a full angular range of calculations of speed differentials versus the angle a measurement is taken at, you'll note that there typically are little to no significant differences up until you exceed 25 or 30 degrees with the parallel. So to account for an officer's location on the right side of a multiple lane freeway, and to accommodate for and cover that entire width, either or both front/rear facing Radar antennae are typically installed at an angle of 20 degrees or so from parallel.
And typically, any officer who is Radar trained and certified is also certified in visual estimate, and his/her testimony will include a visual estimate the always seems to end up within +/- 5 mph of the Radar reading testimony that follows. So how do you refute that?
Who's camera was it that was recording and how do you prove that no one manipulated the recording/playback speed? And when it comes to your measurements using your measuring wheel, when was the last time that was calibrated and how do you authenticate your measurements with any degree of accuracy; an accuracy that you are purporting should rival (or exceed) that of Radar, a technology that has been in use and has been deemed to be sufficiently accurate to convict people of criminal charges in many states ever since the mid 1950s?
Google Maps imaging, even Google earth can skew distances by as much as +/-10% if not more. So while those measurements might be sufficient to estimate an ETA at Grandma's for Sunday supper, you're not getting anywhere in court claiming an accurate speed measurement over ~700 feet of space. At least not more accurate than the officer's visual estimate which was confirmed via Radar.
