Cert. denied in Friedman v. Highland Park, dissent by Thomas and Scalia
Opinion here. The dissent begins after p. 11 of the orders.
A dissent from denial has no precedential value, though it can be cited for whatever strength its reasoning holds. It does serve as a signal (here, by two Justices, one of whom authored Heller) that there are two votes for cert. in a good case raising 2A issues (tho it also signals that the reasons given in this case were insufficient to attract enough votes to grant cert.). It can also signal lower court judges who want to rule in accord with the dissent that there is support for that view on high.
