Your position is common but Machiavellian, and extraordinarily short-sighted.
A primary underlying principal of our government, found throughout the Constitution, is that the processes of justice, law-making, and enforcement must be fair. This same principal does not guarantee fair outcomes. Checks and balances, search warrants, innocent until proven guilty, 5th amendment rights, equal protection clause, etc, are all part of processes designed to protect the innocent and ensure a fair process of enforcement and prosecution of the law. Those processes are full of checks and balances and redress, designed to prevent the exact kinds of abuses the NSA has secretly circumvented.
You are endorsing illegal procedures for all in fear of a handful of terrorists. Anonymous Coward, indeed.
When the government decides, as you have come out in favor, to put aside fair processes in favor of desirable outcomes, it replaces this core principal with "the ends justify the means". In such a Machiavellian guided government, *anything* can be justified. Like assassinating American citizens overseas with drones, spying on millions of Americans, suspension of habeas corpus, stop and frisk, etc.
Your short-shortsightedness ignores the NSA's potential for abuse and the weakening of security for all. You presume the NSA is employing only trustworthy citizens that would not take advantage of their unique powers in order to aid and promote their political affiliations, or enrich themselves through surreptitiously gained information. Evidence already shows your assumption to be wrong, in contradiction to your assertion. If you do not pay attention to the news, perhaps you should research more before posting. But, assume for the moment that there has been no abuse. In your wonderful fantasy of government employees never abusing their powers, why should there be any checks and balances, search warrants, habeas corpus, trials by jury, etc? After all, these things are only necessary if we assume human weakness also affects government employees.
Finally, your anonymous post suggests you may not be real, not interested in exploring the issue, but instead, may be a government astroturfer.
