I understand the thinking but I disagree. We have to fight for every inch we can. By default my take is this : if they're asking me, it's because :

If the full force of the State was on me, it wouldn't take a second for most important things. However, the more people push back, the more they have to divide their forces.

Plus : they may be able to access information in different ways but not be able to use that info in court, or not have the legal right to use it for other purposes unless you consent, etc. As long as we still live in something that still pretends to be based on laws, it still matters, to an extent. We've seen cases where they prefer to drop charges rather than to have to reveal how they came by certain info.

If one is involved in things that are "drone-able" offenses, it won't matter. They'll just Obamacide or Akancide the guy. But for the other stuff, we still have courts. Therefore, they're bound by laws, regulations, and the constitution.
