They were all on the radar.
Do you believe for an instant that being on a "Terror Watch List" would have prevented them carrying out their crimes?
Just publish the list.
Are you in league with Barack Hussein 0bama, Hillary Clinton, Dianne Feinstein, Chuck Schumer, Nancy Pelosi, and Jeh Johnson in favoring secret "No Guns" lists and universal background checks?
No, are you still molesting children?
Yeah, right. And that accomplished what, exactly?
Just publish the list.
OK. I posed a bunch of question upthread about who gets on these lists, how they get there, and how innocent people get off the lists. Can you actually answer them?
No
Right. You at least want the "denial of constitutional rights without due process" lists to be public. It's still a dumb idea, and gives even more power to a government that has proven its untrustworthiness.
