Just because they dealt with guns doesn't mean they used the same tactics.
First, there was a typo in my previous post. Gunrunner started in 2005 not 2007
second, gunwalking was used as a tactic in all three operations. Gunwalking is the tactic everyone is having a problem with.

In March 2006 he signed a contract making him a confidential informant, with the promise that he would be paid unspecified rewards for helping to shut down a weapons pipeline to Mexico. I thought I was doing something good, says Detty, 52, a tall man who favors a basic firing-range wardrobe: solid-colored shirt, khaki trousers, and tan, high-laced combat boots. Beyond any rewards, he would also make a profitin the form of his take from the undercover sales.
Over the next 19 months, Detty sold a series of suspected traffickers some 450 rifles and handgunsAR-15s, knockoff AK-47s, Colt .38sall under the aegis of the ATF investigation. Hundreds of hours of conversations were taped. The guns were tracked, court filings show, and U.S. agents had fleeting contacts with Mexican police. But the investigation did not achieve its ambitious goals. The vast majority of the guns were never recovered by U.S. authorities. No kingpins were apprehended, no cartel taken down. Mexicos drug war raged on.

Same tactic.
That DOES NOT mean "Bush did it too!" Nor does it excuse the ATF and Holder from using the tactic, IN FACT, it makes it WORSE because they tried to use a tactic that had already been proven a failure.
Now there's a good argument against Holder. Doesn't seem like Issa and co. are using it, though. Instead, they seem to prefer to use a half-baked conspiracy theory to rile up the paranoid wingnut base.
There are no conspiracy theory in this cover up.
