Setting a wide scope on bans makes it cheaper for the politicians who create the by-law. Less research is required when you don't have to go into specifics.
If they're going to put a ban in place, I'd like to know what enforcement policy will be like.
I really don't like the restrictive policy of my city. But apparently you have to lose a limb before animal control will deal with you. If that means they'll leave my collection alone, great. But I'd still like to have some help amending the by-laws.
If they only enforce the bans against those owners with multiple complaints, or known husbandry issues, then it might actually be better for the community provided that the media covering the issue is unbiased, rather than sensationalistic. But bad news sells.
