You asked why this sort of violence is taboo, not whether we should break that taboo or not. I’m merely answering your question (“Why is violence in this specific context taboo?”). The answer is because it’s illegal. Everyone understands, either implicitly or explicitly, that the state has a monopoly on violence. Therefore all extralegal violence is taboo. This is a separate issue from whether that violence is moral, just, necessary, etc.

Not true.
For example, many organizations in Mexico do not recognize that the Mexican state has a monopoly on violence. And they actively bring violence upon those who try to claim it on behalf of the state, sometimes successfully.
This is a pedantic comment. So the idea is you should obey the law even when the law is unjust?
