I heard someone on NPR here in DC actually make the argument that the Heller decision, having established that there is an individual right, will actually make it more difficult for groups like the NRA to argue against registration.... because now the government can't legally take away your gun.
I'm all for 100% registration. To be honest, I'm all for laws requiring trigger locks. But I think the individual right in and of itself is good, and SCOTUS was right to uphold it.
If gun ownership is an individual right then government must be very circumspect in regulating it. That is Scalia's argument in his first paragraph. Scalia's opinion gives the NRA very powerful ammunition against gun registration, arguing otherwise is absurd.
