1. Cite a single example of an American citizen suffering
any type of loss or damages resulting from the NSA's actions.
2. Make the case for the US government unilaterally crippling
or disarming it's signals intelligence capability.
This is only because of the actions the US government would certainly take in response, i.e. eliminate various freedoms that still remain.
(I wonder if it's appropriate to speak of 'freedom' anymore? Most of the stuff in the Bill of Rights seems more like revokable privileges at this point.)
Happy to see that you agree. To take your assertion a step further, the US government would likely take such action through the legislative branch, duly elected by US citizens. It is those citizens who would demand that legislators take action.
Even so, a democracy which has voted away all its freedom, still can no longer be described as 'free'.
Also, re-reading your previous post, for part #1, parallel construction means there are numerous, in fact literally uncountable (without top secret clearance, anyway), examples of that. Which, to my mind, is a solid start on #2.
Instead, what we've seen since 9/11 is that the legislators themselves are the ones who are afraid of their own shadow. Just as nobody marched in the streets after 9/11, demanding that George Bush invade Iraq, nobody begged the NSA to implement ubiquitous domestic surveillance capabilities with no effective oversight. These are crimes of opportunity.
