Exactly. The Court made it clear that a ban of commonly used firearms is unconstitutional.
Fenty and his liberal goons don't care that they are violating the law here. They just want to enact a "law" and let someone file suit. The "law" would be upheld by a good liberal judge awaiting trial. The trial would be put on hold for about a year. First judgment would be against the city/district. An appeal would be filed by Fenty's AG and a some liberal judge would uphold the law again awaiting a trial in a appeal. This goes on and on up to the Supremes again and Fenty is hoping Obama has appointed enough liberal justices that his "law" will be upheld!
