Not that I support the GFSZ, I'd like to see it repealed too. Buuuut, that doesn't change the fact that the above story is a poor example of why the GFSZ failed. If only thing, it does the complete opposite. Saying that it failed only because it allowed the hunters to hunt too close to the school.
Bare in mind I'm not really buying the hunter theory, just going by the facts presented. Before attempting to make an argument, one should consider how that argument can be twisted to be used against them, how easily that can happen and pro and cons of preceding with that argument.
