Correct me if I'm wrong but didn't this notion that you could charge federally after a state acquittal arise from the Rodney King case?
Ayn Rand's quote comes to mind...
"The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws"
The first time I recall those type of charges, (which I think are clearly double jeopardy) was during the civil rights era of the 50s and 60s.
No, it goes as far back as the 19th century. The guy who killed Wild Bill Hickock (can’t remember the name) was acquitted then the feds tried him in Federal Indian Territorial court and convicted him. The uses in the early 20th century during prohibition forward are too numerous to list.
