> For instance, someone makes false charge to lock up someone innocent in the name of 'reducing crime', is the issue the goal of justice and low crime or is it the problem with the standards of evidence used to lock up the criminal?

The immediate problem is the troll that is lying and hiding behind a purported agenda. Exposing their real agenda is the immediate fix.

You don’t rhetorically concede to the troll that “reducing crime” is good because they’re a troll. Conceding anything to them is a strategic blunder. They are trolling. It’s irrelevant to the case.
