Lynching is not just another law. It's good to know you're pro lynching.
I tried to explain, I'm not pro-lynching, I'm pro-Constitution. The U.S. constitution does not give the Congress any authority to outlaw lynching in the several states.
Much expansion of Federal authority in the last century has been accomplished under the "commerce clause", i.e., something that Congress wanted to legislate was tarted up as in some remote way a regulation of interstate commerce. As a young boy I was offended by pictures of "Whites Only" drinking fountains in Life Magazine. As a middle-aged man, I dispair of over reaching Federal authority.
