Scott? I don't think we will see a Federal Court agree with any of these State "Firearms Freedom Acts." They are all protest and no real teeth. And that's what this suppressor bill is.
The only way this would ever play to our side (10th Amendment), would be if the vast majority of the States passed similar laws. That just might cause the SCOTUS to actually revisit Wickard. Only by overturning that case, can the Commerce Clause be cabined.
