It seemed to me that the Heller decision left it wide open for government to regulate to their heart’s content - they just can’t ban handguns outright. So if they want to pass laws that state only single-shot pistols of less than .25 caliber will be allowed they can do that. That there will be litigation over this is of no great concern. Government has money to burn and plenty of time.
Just wait until B. Hussain Obama takes office with a filibuster-proof senate and a court packed with leftists.
My reading of the Heller decision was a little different. Yes, it allowed for some regulation but whole classes of guns that are “widely used” cannot be banned outright.
I see this as the DC politicians trying to stick their finger in Scalia’s eye, even if they know such a law won’t last. For them, it’s personal.
