How does that work for something like speeding, where they will charge you with everything, then let you off with a different infraction that doesn't actually have anything to do with the laws you supposedly broke. They do that enough times, and all of a sudden now speeding is legal because no one was charged with speeding, but with "driving with an invalid instrument". This would basically get rid of the "easy plea downs" and basically make fighting against the book the norm. IRL example: I once pulled out of my driveway and passed a stopped school bus (with lights on, but no stop signs extended) on a divided highway (barrier between my side of the road and theirs), a cop saw me do that, went around the barrier and pulled me over a couple minutes later. I was charged with something that was going to instantly take my license away. I went to my local courthouse on the designated day, the prosecuter brought me in and told me he would drop the charges to failure to stop at a stop sign. I said I didn't pass a stop sign, and that the bus didn't have them extended, just stopped with lights on, across a highway from me. Prosecutor said, that I'm allowed to argue that in front of a judge along with paying some large sum, and potentially lose my license, or take a point, and pay $150 today and be done with it. I chose the latter.
