Trial court judge in US v. Miller
I just came across some old email in which I'd contacted the grandson of the district court judge in the Miller case, Hon. Heartsill Ragon, who issued the short ruling striking the NFA, from which the government appealed. The grandson could add little to the ruling -- he never heard his grandfather speak of it, but does add a little human background.
The judge had served on the House Ways and Means Committee, was a conservative Democrat. He served six terms in the US House before coming to the bench. He and the defense attorney, Paul Guttensohn, later became law partners for a time. He was later appointed to the 8th circuit, but the grandson says this was almost contemporaneous with his death.
Here's an online bio.
