This wasn't justice, it was vigilanteism.
Vigilantes are anarchists and as far to the left as one can get.
You have been at FR for a long time and I appreciate your anger at the situation, but a just society is not one in which individuals meet out punishment for those who break the law.
I agree, did you read the last two paragraphs in my comment? My concern is that vigilantism is the outcome of bad law, and the outcome of that is anarchy. Did you read this:
Twisted laws protect the guilty and abandon the innocent. And vigilantism is the outcome. The law must be reformed and liberal judges thrown out or society will descends into anarchy.
