The US intelligence community is in a very poor position to be trusted with protecting civil liberties while engaging in intelligence work. When you're a hammer, everything looks like a nail; when you're a skilled intelligence professional, everything looks like a vital source for collection.

Members of the intelligence community are, it's true, under immense stress to prevent a devastating national catastrophe. I understand a little of how that feels: while working as an analyst in Iraq, thousands of military personnel, contractors and local civilians were dependent on our ability to effectively understand the threats we were facing, and to explain them to US military commanders, the commanders of Iraqi forces and the civilian leadership of both nations.

General Keith Alexander, the former director of the National Security, frequently pushed very hard to "collect it all"; during my time as an intelligence analyst, I completely agreed with his mantra.
