I think the Gun Law guy summed it up pretty well. Asking questions only leads us to more questions.
Things certainly appear to be heading in the right direction for many of us. We would hope that clarification is given sooner rather than later.
Regardless, wherever you live, don't get upset with an FFL who isn't seeing circumstances as free reign to buy and sell supressors without anything more than a 4473. I know if I had an FFL I would prefer caution over exposure to possible sanctions because I followed the advice of some guy on the Interweb.
