There were prosecutions for 12,000 guns being smuggled on their way to Mexico under the Bush plan between 2005 & 2008.<quoted text>
Ok, let's explain some real-world facts to you.
For some reason, Holder and the government of Mexico discussed the program that became "Fast and Furious" in 2009.
Subsequent to that discussion, Eric Holder starts running guns to the Mexican drug cartels.
Let's correct your ignorance.
Bush used GPS units in every gun, and intercepted over 90 percent of the guns before they got to the Mexican drug cartels. Eric Holder ordered the GPS devices not be used, and intercepted ZERO guns before they got to the Mexican drug cartels.
Put these facts together any way you like.
I would think a pretend engineer would know better than think 4,000 is 90% of 250,000.
