Dogs and lack of a "leash law"

There's a dog park right across the street from my college and I think its a great way for dog owners to get thier pets exercise and interaction with thier master as well as other dogs around there.

If your dog is known to not be people friendly, then put on a goddamm leash. I mean it should be common sense, but then again that seems to be an increasingly rare trait in people these days. I am all for leash laws and I hope that they increase the number of places where these laws are enacted, because I'd much rather go through the hassle of a leash, rather then have some poor child get bit by my dog (IF I had one that is).

So, for those who argue "But what about letting the dog run around in the park or something?". I have no problem with that, as long as its a designated area (A Park being one of those areas, or at least the MAIN area), and the owner takes FULL care of thier pet (Meaning if thier pet bites another dog or a person, its THIER fault).

Jam it back in, in the dark.
