At the risk of repeating my comments, I'd like to respond to the JFPO interviewer's concern that Parker allows for government control of guns.

The localities with more liberal guns laws could just as easily have the same strict gun laws as D.C. or Chicago if they chose now. Just because SCOTUS permits a certain level of gun control across the board doesn't require them to enact such laws.

Maybe I'm just ignorant, but nothing SCOTUS decides will force any new gun control laws to be enacted, but merely say they could be.

Since there isn't a decision currently saying they can't enact those laws now, why would they want to do so with a clearer statement from SCOTUS?

Regarding Federal laws that could be challenged, how about the stupid laws regarding sawed off shotguns?

I think (largely due to the fact that I live in Chicago) that a great next step is the incorporation test.
