With jaywalking and driving over the speed limit on one end, and murder on the opposite, you're positive that a motivated prosecutor can't ruin your life?

Everyone does, all the time, without even knowing it. There are so many, and many of them are so broad or vague, that everyone is vulnerable to selective prosecution.

Also, are you telling me you've never broken a law? Never were speeding? Never jaywalked? Never decided you were too drunk to drive, so slept it off in your car?

Lol. You just haven't been scrutinized by government yet.

Also, FYI you're far, far, far better off having real deal criminal prosecutors coming after you trying to get you on a violation of real deal criminal laws because then you have real deal rights with tons of precedent backing them up and literally everyone in the system being trained on how not to violate them lest you get off. If the EPA, your local zoning code enforcer, the parking ticket people, the USDA, etc, etc. come after you you have basically no rights because it's theoretically a civil and not a criminal matter and these organizations are free to unilaterally run their process however unfairly they see fit limited only by what they feel exposes them to risk of politicians trying to reign them in (see also: everyone's complaints with ICE these days). Yeah they can mostly only fine you but if you don't pay (because you dispute) the whole system acts as a ratchet, they lien your house, etc, etc. and you inevitably wind up in court, but with none of the procedural and precedent protection because once again it's non-criminal.

Don't believe me? Try it.
