Good to know - Bummer they didn't just drop the silliness.
When somebody hasn't done anything wrong, and you want to punish them, you don't drop it. You simply sick the dogs on them and ruin them in court through lawyer's fees, lost time, etc. Whether or not you win doesn't matter. You've still ruined them.
Convictions are really only a matter of pride for prosecutors. They can exact any vengeance they want by continually bringing people into court. And good news for them - double-jeopardy doesn't matter anymore. That just got thrown out as well. So, if they don't like a verdict, they just try again now. Either way they win. You either go to prison or you're ruined by the costs of trials. The prosecutor has unlimited funds - you simply can't compete with that, and they know it.
