Rely on the assumption that the prosecutor, judge, and officer do not care about nailing you, specifically, as much as they care about just doing their job and going home. If you make your case seem like more work for them, or if it will end up costing them money to prosecute, they will very likely drop it, even if you are guilty as sin. If I could make 100 deals in the same time it takes to prepare for one trial, I'd throw the trial case on the floor, too. All the good traffic-ticket lawyers will know all the tricks for your state, and some of them are kind enough to give away those tactics for free, essentially as stealth advertising for those who would rather pay the money to ensure a professional will do it correctly.
