To the editor:

Mr. President, you stated last evening, paraphrasing you, if someone throws rocks, etc., you have authorization to use lethal force. Have you heard or read of this:

"The Posse Comitatus Act is a United States federal law signed on June 18, 1878, by President Rutherford B. Hayes. The purpose of the act – in concert with the Insurrection Act of 1807 – is to limit the powers of the federal government in using federal military personnel to enforce domestic policies within the United States. It was passed as an amendment to an army appropriation bill following the end of Reconstruction and was subsequently updated in 1956 and 1981.  The act only specifically applies to the United States Army and, as amended in 1956, the United States Air Force. While the act does not explicitly mention the United States Navy and the United States Marine Corps, the Department of the Navy has prescribed regulations that are generally construed to give the act force with respect to those services as well."

Mr. President, words matter. When you speak from your position, they have greater impact.
