Wow, that's just so many assertions and none of them follow from the statement that the government can break the law in order to protect its citizens. In all of those cases I can just say "they can if it is to protect its citizens". Remember, the premise here is that you are performing the act in order to protect constituents. So before all of those statements you have to assume "They are doing this in the genuine believe that it protects constituents".

The argument so far seems to be "They can do anything, but there are moral absolutes that I can personally list out, and in those cases they can't do those things". That is a hilariously stupid view of the world but sadly a common one.

Even if I grant moral objectivity, I reject that you have epistemic access to it so it's moot.
