> when not skipping bail means you get extradited to a country that will torture you via extended solitary confinement prior to trial

> declared guilty in public by a sitting US president (also before trial)
Because the US has not yet fallen under authoritarian rule and has an independent judiciary, it's possible to have a fair trial even when the president offers an opinion about the case. But offering such opinions is frowned upon because it's bad optics. Before you bring up tainting the jury pool, an upside to the lack of civic engagement amongst Americans is it's not difficult to find people who won't have heard a president's or anyone else's opinions.
