Just heard about this one. Should fire up the faithful. The consensus around here is the guy most likely had been drinking because it is very difficult to miss the border into Mexico. Still, some claim it is plausible. Interstate Freeway Five terminates at the Mexican border, but there are numerous signs warning of the approaching border, a sign that warns last U.S. exit and even a last ditch U-turn that leaves you in U.S. soil.
This guy just blew right up to the Mexico-U.S.A. border at San Ysidro and actually told Mexican Customs that he had three guns in the car. Languishing in the Tijuana Penitentiary System awaiting trial. They will no doubt figure out a way to send him home once he appears before a judge. One funny thing about this story. He actually tried to escape by climbing a wall and the Mexican guard was able to scare him back by firing into the wall instead of trying to kill him. I think he wants the American Embassy to save him.
Tahmooressi’s arrest in Mexico came less than two weeks after arriving in San Diego from Daytona Beach, where he had most recently been living. He had abandoned studies to be a pilot, then a mechanical engineer, and had recently broken up with his girlfriend. He had driven across the country with everything he owned, including a motorcycle, bicycle and three firearms: a 12-gauge shotgun, a .45 caliber pistol, and an AR-15, all registered.
