Biden should now officially order those judges executed. Put in place a law that the supreme court must contain an even split of representatives from both/all major parties.
Then install judges who will reverse the immunity law... Meaning this problem will not come up again.
EDIT: Upon reflection, maybe they just reaffirmed the presumption of innocence for someone who's job it is to sometimes order the deaths of people. So he has "The presumption of immunity" until determined by a court case, or impeachment hearing? Is that what's going on?
It's arguably been been fucked at least as far back as Citizen's United if not longer. Once they opened the floodgates for legalized bribery, there was no coming back.
