One thing that seems to have been overlooked in this case by many of the commentators on the TTAG post linked above is that Abramski lied on his 4473, and he even admitted as such, twice. His lawyers argued that the lie was not material because the uncle went to an FFL and completed the 4473. The Court disagreed, and held that the admitted lie was material. The takeaway — you can’t “cure” the lie no matter what you do. This case should have been more about Abramski committing perjury than the "straw purchaser" angle, but it is what it is.
I fully concur with your take about Kennedy (a member of the Heller 5) switching away from a pro-2A perspective. Not good news for us, especially in any future attempts to get AW bans, magazine capacity restrictions, or CCW laws overturned.
