On to Schumer’s second falsehood — the claim that checks have stopped 1.7 million prohibited sales. In fact, these were only “initial denials,” not people prevented from buying guns.
The Bureau of Alcohol, Tobacco, Firearms and Explosives dropped over 94 percent of those “initial denials” after preliminary reviews. Further review cleared at least a fifth of the other 6 percent.
Truth is, these government databases are rife with flaws. Remember the five times that the late Sen. Ted Kennedy missed flights because his name was on the anti-terror “no fly” list? By Sen. Schumer’s method of counting, that means the “no fly” list stopped five flights by terrorists.

Sure, the 60 Minute program reporting that I mentioned in an earlier posting emphasized the shortcomings of the FBI background checking database, mainly thanks to "garbage in" it as someone else commented.
Maybe you missed it, but further in the article you quote above is the conclusion "Expanded background checks might well be reasonable, but only if the current system is fixed." And Cornyn's bill might help.
