The flip side is true as well. When, long ago, my sister was murdered, I had a discussion with my pastor. Told him I would have no compunction whatever about standing the man up against a wall and blowing his brains out myself (and I meant it.)
He said, "That's why we have a justice system."
What happens when the “justice system” fails, or simply refuses to do its job?
We’re past that point in many jurisdictions.
