So Pres. Obama's appointee for State Department legal advisor likes gun bans,

but we're not supposed to be worried...
In this article, Koh lauds the international gun control effort, and criticizes John Bolton's invocation of the Second Amendment at the 2001 UN small arms conference.
Yeah, I mean how DARE we bring up that our highest law notes a right to arms? We were supposed to bend over for the UN!

But Obama & Co. aren't out to ban things, noooooo.
2) You have argued in your writings that transnational legal processes can and should be used to develop and eventually “bring international law home” to have binding force within the U.S. legal system. Do you think it is appropriate as Legal Advisor to support such efforts to use litigation to incorporate international legal norms within U.S. law?
Which would allow Obama to say "International law says that guns like (fill in the blank) are banned from private ownership, so turn them in." And do we want this being used to force what the UN and 'international law' says about self-defense on us?
...
4) You have written vigorously in defense of the view that customary international law has the status of federal common law within the U.S. legal system. Do you therefore also believe that the President has the power to invoke CIL to preempt state law, as some scholars have suggested?
Which would mean, if he thinks so, that he wants the President to be able to use 'international law' to say "I don't care what your state law says, International Law say THIS, so that's what holds."
But don't be worried, no.....
