Congress: US repeated 9/11 slips in Christmas plot

WASHINGTON — Despite a top-to-bottom overhaul of the intelligence community after the 2001 terror attacks, the security system showed some of the same failures nearly a decade later and allowed a would-be bomber to slip aboard an airliner, congressional investigators said Tuesday.
The Senate intelligence Committee report at times contradicted the Obama administration's assertion that the potentially catastrophic Christmas Day bombing attempt was unlike 9/11 because it represented a failure to understand intelligence, not a failure to collect and understand it.
