Terance Gamble was a felon who believed he still had his 2nd amendment rights, apparently. But legally, he did not. Felons aren’t allowed to have guns, y’all.
Gamble said, “Fuck you, I’m getting a gun.” And, so he did. His dumb ass got pulled over, and the cops found his gat.
Alabama threw his ass in jail for a year, in violation of the law which prevents felons from having a gun. Additionally, federal prosecutors decided that wanted to tack on another 34 months, because they ain’t playin’, dog.
Gamble was like, “Hold the fuck on a minute. Double jeopardy you sonsabitches! The 5th amendment protects me from this shit. I can’t be tried twice for the same crime.”
So SCOTUS was asked to determine if double jeopardy only applies to one government entity, or all government entities within the United States. One prosecution was by Alabama, one by the United States, something they called separate sovereigns.
SCOTUS sided 7-2 for the United States. Neil Gorsuch and Notorius RBG correctly (IMO) sided with Gamble. This decision makes my libertarian butthole hurt.
