That went out with Rodney King. The cops were not guilty so they tried them again. They just did the same thing in Michigan.
Now our criminal occupation government tries you till they get the verdict they want. THEY get to decide wjat is double jeopardy and do not give a flying fornication what the founders would have recognized.
Their other trick is multiple prosecutions in several jurisdictions as they are doing with Trump. They pick their target and launch cases simultaneously in Georgia, DC, NYC, etc. The cherry in top is that they raid the target’s attorneys offices and make it impossible for them to get legal representation.

It will stop when people start going Solzhenitsyn on the legal operatives.

And if all else fails there is the old fallback of Federal Civil Rights violations.
