M. Esther Barber, who eight years ago tugged at the heartstrings of those of us who attended an Indianapolis immigration summit with her tale of harassment by the Mexican Consulate but several years later discovered there was money to be made in aiding and abetting illegal aliens, has been sued by the state's Attorney General Greg Zoeller for offering immigrant services without having the proper training or licensing.   Said Zoeller: "To profit from immigrants' desperation over their legal status is considered 'exploitation' in any language. "In both lawsuits, my office is asking the court to stop these defendants from taking money from consumers for services they legally cannot provide." Memo to Mrs. Barber:  You and your late husband betrayed those of us who befriended you - and your country - by joining the other side in opposing attempts to enforce our immigration laws that were created to protect American workers.  To borrow a line I learned from an Army drill sergeant, "If you're looking for sympathy, you'll find it in the dictionary between suicide and syphilis."
