Congress neglected to substantiate their finding of substantial effects in the Gun Free Schools Act. In Lopez they had extensive documentation to support the claim, but the court didn't buy it.
When the CSA was passed, the standard was that a finding of "substantial effect" by Congress was sufficient in and of itself, and the court would defer to Congress on that finding. Wickard v Filburn gave Congress a blank check. It's time to close the account.
I totally agree. I just don't think it's gonna happen. Hope I'm wrong.
