So if I design and build a bridge using sub-standard materials and the city discovers it before it collapses and kills people, you shouldn't be able to charge me? There are lots of areas of law where this concept, or similar ones, crop up - that's all I'm saying. Pretending it "doesn't make sense" is illogical, because we've made (legal) sense of it.
