Perhaps he can use this:

"It is expressly provided in the Constitution of the United States, that the States may provide for their own defence in times of imminent danger. We are bound by that Constitution and we have a right to defend ourselves in the way that is reserved in the Constitution of the United States; that is left to every State in the Union, unrestricted and in full force. He knew that the people of the United States had reserved the right of self defence; but the States have given up the right to keep ships of war or troops in time of peace. What he had said he took from the book, and he had not gone beyond that. The right of preparing for war is exclusively reserved to the Government of the United States, and the States cannot, for their own defence, keep ships of war or troops in time of peace. Now for the qualification of these remarks, he would refer to the amendment to the Constitution which had already been read as follows: "A well regulated militia being necessary to the security of a free State, the right of the people to keep and bear arms, shall not be infringed." Why this was intended to convey to individuals certain personal rights. This is a personal right reserved to individuals to bear arms; this was adopted to grant to every man the shield of self defence."
