> <i>The briefing was meant to convince lawmakers that the surveillance programs are legal and necessary in fighting counterterrorism</i><p>First, I don't think you want to fight counterterrorism, but, rather, terrorism?<p>And second, what's with this business of "legal and necessary"? It doesn't matter if it's "necessary", it doesn't matter if it's really really super useful, it doesn't matter if it's very efficient. The only thing that matters -- that should matter, in a democracy -- is whether it's legal and constitutional.<p>The moment you let "efficiency" step over legality you let the beast loose, and the results are drone killings and surveillance programs.<p>Drone killings are a hundred million times worse than surveillance, BTW, and somehow make less of a scandal.
