Just so you know, I find your unwarranted contemptuous tone offensive.
To your points. I am not suggesting that action taken by innocents (or guilties) harmed by abuse of executive powers expanded because of security reasons is adequate protection for those individuals. Rather it acts as an ultimate check on the system of executive power. (as one of several.) Clear abuse foisted on innocents with a cause of action will motivate the courts and congress. Discovery follows a cause of action. As some courts have found, the sort of abstract rights fishing that typifies cases brought to date, fail for this reason, not because the court in principle denies discovery, but rather that there is no cause of action.
Consider the Dukie situation. The full panoply of rights enforced bu a cordon of expensive lawyers did not protect the Dukies from harm imposed by an abusive prosecutor. But that harm provided a cause of action which led to discovery of the abuse and the punishment of the abuser.
Further, the guiltys in these instances are specifically people who we want to stop from killing thousands. If executive action is in fact focused correctly on such people, I don't believe it is remotely acceptable that they receive the same protections and deference as say a single crime wife murderer. If the law does does not allow different treatment of such people, then the law becomes a suicide pact. But I don't think we're there. The law, notwithstanding you argument does allow different treatment. The question at hand is how far to go.
