Where? 

I surrender. Non-attorneys have decided an entry on a genuine court case is the place to reargue the case.

Nonsense like this is why Wikipedia can't rise to the level of a reference work.

"I don't remember them explicitly addressing ..." - you do understand that this *was* an entry on Parker v District of Columbia, not Chemerinsky's ideas? No? No suprise there.

Have fun in sandbox, children.
