The link takes you to a media press release. Some excerpts:

Washington, D.C. – Eighteen years ago today, on November 30, 1993, President Bill Clinton was joined by Jim and Sarah Brady and many others in the White House for the signing of the Brady Law, the landmark legislation that instituted criminal background checks on firearm purchases from federally licensed gun dealers and created the National Instant Criminal Background Check System (NICS). The bill signing in 1993 was an emotional capstone for Jim and Sarah Brady, who fought bravely and tirelessly to pass the Brady law after Jim was severely wounded in the 1981 assassination attempt on President Ronald Reagan.

On February 28, 1994, the law started blocking handgun purchases by felons and other legally prohibited buyers, such as fugitives from justice.   For the first five years of the law, authorities had up to 5 business days to complete background checks while the FBI built the computerized system to conduct the checks.

Let’s go over the whole thing again: Brady Campaign is telling you straight to your face that the NICS check and the Five Day Waiting Period would have stopped John Hinckley. Stop. Nothing and nobody can argue that….except the facts: Hinckley was not a Felon, had not been determined mentally incompetent before the shooting and the gun was bought six months before the assassination attempt.

One more thing on the media press release:

Through the end of December 2009, the latest year for which data is available, the Brady law had blocked over 1.9 million attempts to purchase a gun by legally prohibited purchasers at gun dealers

And that is an outright lie. Brady fails to inform that immense majority (way over the 90 percentile) of those “blocks” were false positives by either data input error at the time of purchase or other mistakes. If truly 1.9 million felons were stopped from buying guns, it means 1.9 million federal cases that had either be taken to trial or pleaded for violating 18 U.S.c. §§ 92] et. seq., are punishable by up to 10 years imprisonment and/or up to a $250,000 fine as printed on top of ATF form 4473 which is done in every firearms transaction with a Federal Firearms Licensee.

At the first anniversary of the Brady Bill, Then president Bill Clinton said:

Well, now we know that, as the Secretary said, over 40,000 convicted felons, fugitives, drug dealers, gang members, stalkers, were prevented from purchasing handguns in the Brady law’s first 11 months. I should point out that the real national number is bigger than that because, as you know, there are some States that have companion laws that go along with that. And the estimates are that, nationwide in the States with Brady-like laws and the Brady law, the total is more like 70,000.

Amazingly so, there were only four prosecutions for violation of the Brady Bill during the same time period with a grand total of zero convictions.In fact during CYs 2002 and 2003, only 154 (less than 1 percent) of the 120,000 persons who were denied during the NICS background check were prosecuted.

But wait, there is more! The press release said that the Brady Law helped block 1.9 million attempts to to purchase a gun by legally prohibited purchasers at gun dealers. Yet the FBI reports that between November 30, 1998 to October 31, 2011 there was a grand total of 882,447 denials. This is half the number Brady Campaign is touting, why the need to inflate them?The reason is simple: The Brady Law was heavily advertised by both Government and the Media as the solution to all gun problems and pushed through Congress.The moment it was signed by president Clinton, they changed the tune to “A good first step” indicating that more gun control measures were on the way. Yes, they lied. Then  statistics started to come in and

The Review of the Bureau of Alcohol, Tobacco, Firearms and Explosives’ Enforcement of Brady Act Violations Identified Through the National Instant Criminal Background Check System. Report Number I-2004-006. July 2004 states the following:

Our review also found that few NICS cases are prosecuted. During CYs 2002 and 2003, only 154 (less than 1 percent) of the 120,000 persons who were denied during the NICS background check were prosecuted.

You want to know the total number of NICS checks for 2002 and 2003? 16,935,910. If my math is not too bad, that means only 0.0009% of the total NICS checks for those years were prosecutable.

There is more to the Brady Law, but this should suffice for now. If you are not convinced by now of the capability of the Brady Campaign to lie through their teeth and their desire to treat Law Abiding Citizens like criminals, I don’t know what else can.
