Who Pulls The Strings At Border Patrol?

Michelle Malkin has a look at "the longstanding battle between DHS management and rank-and-file employees over strict, tough, and unapologetic immigration enforcement." Her extensive summary comes on the heels of accusations that the Mexican government is being tipped off by U.S. Border Patrol as to where the Minutemen (civilian border watchers, a.k.a. Undocumented Border Agents) have been patrolling and detaining illegal immigrants. DHS denies these allegations, but by Malkin's account, not very convincingly. She makes the case that the Mexican consulate has more pull with the Department of Homeland Security than do the field agents and citizens who patrol our borders. It does make me wonder why we have a border patrol at all, if their effectiveness is being hindered from the top down.
