Intrepid Border Patrol agents detained a 96-year-old former judge, Arizona governor and US ambassador to three countries for almost an hour in a tent in 100-degree heat, wearing a suit, en route to a birthday party, after his pacemaker apparently set off a radiation sensor. Raul Castro - no relation to the other one - was Arizona's first and only Hispanic governor. Clearly, at this rate, he will be its last. And he's been stopped twice before.
