Yet I don’t see how such an attack would have been prevented by charging the (supposed) registrant’s landlord $5k per year and limiting him to one tenant per 1000 square feet (you know, like Louisiana prisons).

I wouldn’t be surprised if the plaintiff here is a slumlord renting to registrants well above market value for lack of any other registry compliant housing available. But even so, I hope he makes the parish council choke on this idiotic ordinance.
