Even if the Patriot Act isn’t renewed today, it’s not going to make any difference.
Torture was always illegal, but the government wanted to do it, so they did it. Not only were the people who did it not prosecuted, they got medals for it.
If the Patriot Act isn’t renewed, the government spooks aren’t going to sigh deeply, close their notebooks, and go home.
They want to do this, so they will.
