TWO YEARS AGO, American hikers Shane Bauer and Josh Fattal, both 29, were arrested by Iranian officials along the Iraqi border. They have been jailed ever since in Iran s notorious Evin Prison. Bauer s fiancee, Sarah Shourd, who had accompanied them and was also arrested, was released on bail more than a year later. According to lawyers for the still-detained men, a verdict in their trial could come within a week. It is time for Iran to let them go.
