The goa filed a amicus brief but was the only group to ask for a narrow view of the Second Amendment. Gee, thanks for nothing, goa. Now we have to file 20,000 lawsuits to get rid of 20,000 gun laws.
Even small groups like the Second Amendment Sister have more brains than that.
The goa is nothing more than a t-shirt company.
Heller's own attorney argued for a narrow view. But as I read the GOA brief, they were merely trying to counter the Solicitor General's view that a decision for Heller would invalidate all current laws, while at the same time pointing out that Congress has no power to pass such laws, such as against particularly dangerous weapons, in the first place, because they do not have the general police power.
Mainly though they just argued for the Court doing what it would do anyway, rule only on the case before it, without consideration of other laws, be they federal or local.
