Even before the border was flung open, federal law enforcement failed time and again to prevent mass casualty attacks by terrorists.
Do you remember the D.C. sniper attacks? In October 2002, John Allen Muhammad and Lee Boyd Malvo went on a protracted shooting spree in the Washington metropolitan area, during which they murdered 10 people, wounded three others, and disrupted the lives and daily routines of hundreds of thousands who feared being the next randomly selected victim.
It took three weeks to track down and capture Muhammad and Malvo. But, before they were caught, the killers tied up massive federal, state, and local law enforcement resources and terrorized Washington and its suburbs in Maryland and Northern Virginia.
