Several days ago, in the damage control aftermath of Snowden's NSA espionage conspiracy fact confirmation, Barack Obama took to the TV pulpit where he appealed to the nation, as he always does in times of strife, explaining that one can't have 100% security and 100% privacy. He said some other things, all of which as usual wrapped in rhetorical brilliance, if holding little of pragmatic and realistic value. So who better the debate the president's attempts at damage control than the vice president himself. Here, for your viewing pleasure, is Joe Biden, circa 2013 debating Barack Obama, circa 2013.
As for the false dichotomy between security and personal privacy and liberty, old Ben said it best.
