Unfortunately, when you are subjugated under a legal system based in finances and not living with a justice system then there will always be vigilante justice as it is the only way for justice to be served.
There are and have been some hideous wrong doings in the commission of vigilantism but they are also countered by the vast majority of court sanctioned misscarriages of “justice.”
How many were hanged innocently? How many jailed for no reason? How many corporations trample the unwashed masses in their thirst for money and use the courts and scum lawyers to do it?
I’m not arguing that what these dipshits did was right but there is a reason why, it is the utter failiure of the legal system over a justice system and the people it is supposed to serve and protect.
