The move to introduce, pass, and implement this ordinance is a rush job as the City of Chicago freely admits. Jeff Levine of the City of Chicago's Law Department had this to say:
But Levine said the 7th Circuit Court of Appeals could rule on the lawsuits at any time, making it important for the city to get its own firing range rules on the books. The city hopes the appellate judges will opt not to intervene if Chicago has a firing range law in place, Levine said.As Sebastian noted last night, Alan Gura does not think this ordinance should moot Ezell v. Chicago.
