1/ “Innocent until proven guilty” is a core principle of justice. If you’re tried in a court of law there are rules of due process: the defendant’s lawyer gets to cross-examine the accuser, defendant gets to bring his or her own witnesses, circumstantial evidence investigated etc

2/ But when you’re tried in the media or on social media the court of public opinion can be vicious and cruel these days. Just because someone said something, that doesn’t necessarily mean it’s true! Gossip isn’t evidence. Accountability is one thing, but mob justice is another.

What you describe is not the political system; it’s a perversion of the legal system. Cops executing people is not the legal system; it’s murder. The legal system is their being arrested and tried.
