In general, I don't either. What I have an issue with in this case is not the unconstitutional rules - because those were not challenged anywhere IN the case. The reason I take issue with the case is because the buyer was perfectly fine with the "rules" until they bit him in the ass, and then in the end he bounced through multiple "reasons" why he should not be held to account to rules he followed (albeit dishonestly). Under the law, the decision was the correct one. Whether the law itself is constitutional is another matter - but one that NEVER came up. What he should have done is challenged whether or not such a form is legal - especially since an answer of "no" would infringe upon his right to gain access to the firearm. The mere fact he went through numerous excuses tells me this was never really about a constitutional question to start with. He fibbed, got busted, and tried to whine his way out of it. That isn't how our forefathers would have dealt with an unconstitutional or unlawful rule.
*Read the Declaration of Arms - they challenged the existing power structure while working within it. Did they pay illegal taxes in part while whining, or did they say "hey, this isn't right, we won't do it (dump tea here) and look at government in the face with a deadly earnest? I think we know the answer....*
Where we won't agree is whether Courts should be going outside the question before them. Doing so has created the problem of legislating form the Bench - and they shouldn't be doing it - regardless of whether its a "win" or a "loss" on a subject I care about. Whether they do it or not - we both know they do. Should they? Absolutely not. It is that action that has made them part legislature - which was never their constitutional purpose.
While I agree the form is a violation of the Constitution, I can see background checks as an infringement as well. At least, if one is denied the right to purchase. The same could be said for "may issue" states when it comes to permitting. A refusal to permit a person to carry - or even the requirement that they go to some "government approved" class to get such a permit - is an infringement.
