Yes there are threats out there, I will not deny that.
What makes me uncomfortable is how far we should go to counter them?

Having such power and no checks is asking for abuse.
I also think that having too much power will make it easy for people to be sloppy with the term "terrorist". Be too critical of the govt and you could be labeled a "terrorist".

Do not forget the other abuses of power here in the US, the wrongful internment of Japanese Americans or the "Red Scare" of Senator McCarthy. Those are just the 2 I remember, bet there are more.

Asking for assurances that the people who protect us from threats that they do not abuse their power is not the same as rooting for the enemy or being a terrorist tool.
