Rather than answer each similar observation, I just point out that you guys are all so willing to bet so many people's lives on your assumptions.. people that, over and over, tell their legislators that they don't like the way you think. You are also misunderstanding how this web of information could be used, whether deliberately or not, I couldn't say.
We have proven methods, committed killers, and unnetworked intelligence capable of, in many cases, smoking them out. But you are so concerned about your right to not have this information available to DHS that you will merrily put everyone at risk.
