Parker v DC 

I just looked at my comments, and "Wikipedia policy be damned" doesn't appear there. The policy you cited as an excuse for loading up irrelevant commentary doesn't compel leaving such rubbish in the entry.

What you're doing is finding materials that regurgitate either the Court's dissent or arguments in dissent and posting them under "Controversy".

I appreciate not everyone is pleased with the Court's decision.

The place for their arguments is either before the entire Circuit Court if it grants a hearing, or before the Supreme Court if it goes there.

For example, Chemerinsky's rejection of the Court's plain English decision doesn't deserve a full paragraph. Chemerinsky has an argument, the Court considered it as proposed by the parties and amici curae, and rejected it. He, and you, should accept that and gear up for the next hearing, if any. Basically he "argued that the ruling had 'no basis in constitutional law'." Your propose long quote adds nothing of substance to that.

Take a look at the article on the Second Amendment for an example of how to handle it.
