Apparently the Navy Yard murderer lied about his previous gun arrests and about significant personal debt when he applied for his security clearance. Worse yet, the Feds knew this, knew he lied and turned a blind eye to it.
"Then federal investigators dismissed the omissions, and made one of their own — deleting any reference to Aaron Alexis' use of a gun in that arrest."
I wonder, could the massive failures here have had something to do with the Obama administration's policy of "Oh my god! Doing background checks on employees is sooooo racist" I'm sure of course that the Obama administration's position on universal background checks on gun sales is not "racist" despite their clearly disparate impact on blacks.
