Janet Napolitano's former chief-of-staff one of many at center of Fast and Furious scandal

Homeland Security Secretary Janet Napolitano was in Nogales, Arizona on Thursday to announce the Obama administration's intention to strengthen efforts to stem the flow of drugs, arms and drug money on the southern border.  This in the wake of the Fast and Furious scandal and subsequent Congressional investigation which has top officials at the Bureau of Alcohol, Tobacco and Firearms and the Department of Justice (including Attorney General Eric Holder) running for cover

A new story line in the broken wheel of Fast and Furious is the role played by the U.S. Attorney for Arizona Dennis Burke.  Burke, appointed to the position by President Obama soon after his election, is a long time aide to Napolitano.  He most recently served   as her chief-of-staff when she was Governor of Arizona.  Burke, who worked in the 1990's to ban automatic weapons, is reported to have provided "legal guidance" to the ATF on the operation that allowed guns purchased in Arizona to make their way into the hands of drug cartel members in Mexico.  One of those guns was used in a shootout that took the life a border patrol agent Brian Terry.

At this point in the investigation, a lot of finger pointing is going on.  It seems quite a few of those fingers are tied to a slew of dirty hands -- maybe even at the White House cabinet level and beyond.
