Since you fail to see the humor in this plan of attack, I'll point it out for you.
You see, his job is to be in court prosecuting people just like you, who have been caught breaking the law, this is where he spends his time productively. Furthermore, he's paid for being there, it does not cost him any money.
Now, do you see the irony in your strategy?
So basically, it will cost you time and money. In other words you will be asking him to reduce your charges to littering so that you don't have to waste time and money defending yourself. So, how much leverage do you honestly believe you will have with this plan of attack?
