I believe Fast and Furious was the name the ATF designated to the program for internal correspondence. Gunwalker was something the justice department used to describe it in their communications.
It was called “Project GunRUNNER” by ATF, “GunWALKER” was used as an ironic term by those reporting on the fiasco.

One can only guess why Holder would want arms from US dealers killing Hispanics in Mexico, but the propaganda barry bassturd's admin fed to the whoreish media about most of the arms in cartels coming from America might be a clue as to what Holder and company were trying to accomplish.
Conflating the two distinctly different programs is now the talking points approach to connect this to Bush and absolve the criminal democrats of their crimes. Don't help them establish this blatant lie.
