100% true. This is the history of lynching in America. Community murders where nobody saw a thing, and the justification was always that the murdered person was a degenerate who would not receive what the town thinks would be adequate punishment under the law.
Grotesque but the fact is that these public square hangings were done since medieval times and probably earlier. From the Salem witch trials to the San Francisco vigilantes, it happened in many town squares, and it was believed to be justified: https://www.legendsofamerica.com/ah-lynching/2/
These weren't all that long ago. Someone claimed that there are people walking around today that went to one of these events. I couldn't corroborate that claim but we're talking less than a hundred years ago. While the Middle ages were some 5-900 years ago.
Also what makes these public killings so notable is the fact that it was a deliberate effort of an entire society to instill fear into a minority. That you don't see very often. There wasn't even an attempt at justice, they didn't even try to make it seem like these people weren't being killed just because of the color of their skin.

I prefer the version of history suggested by the last sentence, but unfortunately cannot accept it was accurate.
Looking around the world, I see it frequently and with broad geographic distribution. (Though it's not the whole society, just the dominant group, both in the immediate example and the general case across time and space.)
No, they were always accused of rape, murder or something substantial. Read the article I posted above. I suspect that in some cases, they were correct in their accusations. That being said, I don't believe in the death penalty for a lot of reasons, not least of which is this tendency of humans to seek "justice" with often little evidence at all.
