Failing to share information makes us weaker. It enfeebles congressional oversight, which is a cornerstone of representative democracy and which, when aggressively carried out by fully informed legislators, can strengthen policy-making.
One of the fundamental lessons of the 9/11 tragedy was that our government carried a share of blame for the failure to stop the attacks. Not because it was asleep at the switch or ignorant of the dangers that Al Qaeda posed, but because the agencies charged with our safety did not share what they knew, either up and down the chain of command or with each other.
