Incorrect, the reason we don't live in the reality you describe is witness testimony is unreliable, and mob justice fails every time it's tried.
You are innocent until proven guilty. Period. Otherwise I can just say you killed my uncle and kill you in response to that made up event.
Given the ridiculous amount of money being poured into anti green sentiment and lawsuits by the Dems, it seems like they're threatened.
Maybe we can have a somewhat left wing party when Dems lose again and can't blame the greens or Bernie bros or other scape goats for their own failure to represent popular policies.
