If trust doesn't currently factor into downzapping, it probably should. I suspect it's easier to outlaw stuff for those with high trust.
I've never thought about that before, and I'm not sure if it should be a factor. @k00b is the one who can clarify how it currently works.
I also have Wild West mode on and I've noticed more outlawed stuff since we started talking about this, a few days ago. It seems like a simple reminder was enough to activate downzappers.
