Has Venice ever had a major problem with "urban campers" such that they would've had these laws? I live in a place not dissimilar from Venice, lots of tourists to pan-handle from, and we've had similar problems. It's unfortunate that they clobbered tourists with such an excessive fine, i.e. shouldn't first-timers be shown lenience in case of simple ignorance and misunderstanding, but the fact folks will find lenient areas, flock to those areas, and that ends up causing problems for the folks that live in the area.
