Our political parties are failing us so badly, I wouldn't be surprised if the guillotine came back into fashion over the next decade. I hope congress can get its act together and serve its constituents better before it comes to that, but it feels naive.
So many books cover the hideous nature of mob justice, so-called "revolutions", and their gruesome knock-on effects, there's really no excuse to be this undereducated about what you're saying.
