The legal responsibility angle of this all always leave my head spinning.

If you let your dog off leash in a place where it is illegal to do so, congratulations: you've just lost the lawsuit.

If anything remotely funny happens -- regardless of what -- the liability can and will fall on the dog-owner for their reckless behavior. The real sad part of this is when the dog gets put down for the stupid owner...but my point is the people who let their dogs off leash have also posted a big, red sign saying "I'm responsible for anything happening here" -- even though few of them seem aware of that fact. Liability only becomes a question again if there is another dog-owner with their dog off leash.

Dogs should be treated like guns and other weapons. If a person gets a fine or jail time for shooting someone, a dog owner should get the same if their dog bites someone. If my gun would be taken away if I rubbed it in someone's crotch, then a dog should be taken away if it sticks its snout in someone's crotch. Perhaps one would say "it's not the owner's fault, the dog makes it's own decisions", well that makes it worse. my gun doesn't aim and fire itself. So maybe dogs should be regulated even more than guns.
