One thing many folks are not aware of is that double jeopardy, the legal concept by which an individual can only be tried once for the same crime, does not apply across jurisdictions. While it is exceedingly rare for the federal government to pursue a prosecution that was already lost at the state level, it is much more likely in cases when the defendant is acquitted. It is also more likely in cases where the federal government has a valid reason to pursue the charges under federal law, and the cases they do pursue after failed state prosecutions tend to be high-profile high-stakes cases like Rittenhouse’s trial.
The jury was made aware by the judge that if they convicted Rittenhouse on any of the homicide charges, it would reduce the likelihood of a second trial filed by the federal government. On the other hand, it increased the possibility that Rittenhouse would be convicted in this trial. In other words, the jurors were instructed as to the consequences of their decision.
