The US government and the sale of guns to Mexican drug cartels

Here is John Stewart's satirical take on BATFE's Operation Fast and Furious:



Some questions I feel compelled to ask are:

• Why are Representative Darrell Issa and Senator Charles Grassley virtually alone in investigating this scandal?
• Why does every other congressman apparently endorse or at least tolerate the arrogant defiance of, and refusal to cooperate with, Congress by the Department of Justice (DOJ) and the Bureau of Alcohol, Tobacco, and Firearms (ATF)?

Congress supposedly represents the people. Therefore, DOJ and ATF are, as usual, defying the people of the United States!

Voters, is this really the change and transparency that you expected from the current administration and for which you voted?
