I see. So, for example, if there is a well-publicized case about illegal firearm sales, the judge should really come down hard on all subsequent firearm sales. Sure.
This collective guilt baloney has got to go.
It isn't collective guilt that is at issue, but collective risk--risk of death and serious injury. The community should not have to tolerate that risk. The judge has a duty to push the responsibility back onto the plate of those created the risk.
