Here's my take... The defense of proof the radar was calibrated and up to date, tuning forks used at the proper times, use of sound for tracking, etc, etc, is actually true. Problem is, we all train for that and are ready to testify to that today. We learn too....lol
I actually have the new Cobra that blue tooths to my Iphone. Nice gimmick, it seems to work, but it is more of a electronic social network. It might save you it might not...especially with 'instand on"...
I would be first to admit, there are jurisdictions that use citations for revenue. Thank goodness, none around here. But they do exist. I can think of one in Illinios before you get to St. Louis on I-70. I met one of those guys at a McDonalds...lol
One of you guys hit the nail on the head with judges. Our judges will ask at the beginning of court, if you think you are pleading not guilty to speed because you think the officer was wrong, be ready to prove it. Because if you think you were doing 35 in a 30 but the officer wrote it for more, it doesn't matter, because you were still speeding...speeding is speeding...
