Now, please, don't get me wrong, I'm not of the opinion the intrusion is right, or even justified in 100% of the cases, I'm merely pointing out again and again that the situation, potential inadvertent consequences, and even the rules and laws are more complex than the knee jerk reactions that the press is creating.
My initial admonishment is that the arguments and reactions I keep seeing are reminiscent of non-gun folks making arguments for gun control, without digging into the cause/effect, technology, existing laws, etc.
The reason we have had court rulings on common carrier and metadata (eg civilian courts regarding LUDS) is because those issues have arisen before. If we need to revisit them, fine, but just as those decisions created these potential effects, one must also consider the effects of changing it, and if possible, understand what the "it" truly is.
Hell, I've seen people quoting news articles, quoting people, quoting people who spoke in classified meetings (no transcript of course) and treating it without context as fact, and neglecting words like "could" as opposed to "do"...where have I seen that before?
