Just a thought here, but how about turning him over to the families of the victims. Some frontier justice might be a better deterrent. Maybe some of those Mexicans killed have cartel relatives?
Well, given that thanks to Obomba and Holder they have many AR styled weapons, I think that would work. Hopefully after they take about 24 hours with him with a blow torch and pliers to make sure he had no accomplices. Maybe we could program him to say that Hitlery and he were close, just a thought.
