I get sick and tired of people trying to dodge charges on simple technicalities
One thing I've learned is that "technicality" is a word that prosecutors use when they really mean "he didn't break the law, or we broke it trying to prosecute." For instance, consider that most antis consider post-ban ARs to be built on "technicality" by not including the evil features. Their "technicality" is our strict reading of the law. Similarly, when a judge throws out a case because the prosecutor abused the accused, the "technicality" is when the government "technically" broke the law by infringing upon the accused's rights. Bottom line is, "technicality" is a weasel-word used by prosecutors and people who don't believe in rights, presumtion of innocence, and other such things.
As for a DUI, you don't want that on your record. Even if you think you'll be OK, you're probably wrong. Ever think about learning to fly? If you have ever--in your entire life--had a DUI, you have to report it to the FAA.
For life. In some states, I understand that a DUI makes life as a firearms owner difficult, particularly WRT concealed carry. Many of the neo-prohibitionists are also working to pass ever-stricter laws about alcohol. I could tell you of a few here in Norman, and you'd drop your jaw--things like forfeiture of your property if anybody is ever caught drinking underage on it,
even if you rent the property to somebody else, as a landlord. Given things like the Lautenberg amendment, felony prohibition in general, retroactive copyright extensions, and any number of other retroactively-applied law, even being alright now is no guarantee of the future.
It's too risky not to fight this. You say yourself that you've come clean. That's good. In theory, the entire purpose of our "corrections" system (the government's own name, I remind you) is to show people the error of their ways, and convince them to change their behavior.
You've done that, so the system has accomplished what it set out to accomplish. There's no sense whatsoever in allowing such a conviction to be placed on your record.
Besides which, the prosecutor sounds like a sleazebag, what with waiting until the last few days, and under no circumstances should any decent citizen
ever help a sleazy government official. It's just plain unamerican.
