They are two separate programs.
Now I'm confused...how is this program different than Gunwalker?
It certainly is confusing. My interpretation:
Project Gunrunner - Started in GWB administration, had some success
Operation Fast and Furious - Offshoot/part of Project Gunrunner, re-purposed to support Obama's lie that 90% of the cartels' guns were coming from US
Project Gunwalker - a blogger's nickname for Operation Fast and Furious which plays on the original project's Gunrunner name and the fact that US agents allowed/facilitated the guns walking across the border
Project Gunrunner, often referred to with the sarcastic term "Gunwalker" is an ATF program that started in the mid 2000's. FFL's (Federal Firearms Licensees) in the border areas were asked to report suspicious transactions and those weapons would be entered into an ATF tracking database. When possible the suspected straw purchaser was tracked down and arrested.
Operation Fast and Furious is an offshoot of the Gunrunner program based in Phoenix. It was essentially an expansion of the Gunrunner MO with the stated purpose of tracking weapons to drug cartels. The difference with F&F is that ATF didn't arrest anyone. The weapons got sold, were entered in the database and accounted for only when they showed up at a crime scene....such as the shooting of Brian Terry.

They are the same program.
What do you expect from Fed Bureaucrats.
