I can't even fathom what's happened here, and it seems there's one obvious conclusion: US democracy is effectively over, we're just waiting for the curtains.

Combining that with the pretty much arbitrary immunity SCOTUS decided Presidents get, the President is effectively untouchable now? Have I misinterpreted something?
