His appeals for tougher sentencing and weakening privacy have been consistent since the late 70s, and have outlived their popularity even with the kinds of people who fund him. He put a lot of work into what became the Patriot Act for over a decade before it became a reality. Very few politicians stick to something for so long and work so hard to get there. I'm inclined to believe that his actions demonstrate his revealed preference, as the Austrian Economists would say.

In fact, it would have been politically expedient last summer for him to say the 1994 crime bill was a mistake in hindsight, but he did the opposite. I think this is who he really is.
