According to the Sunday Star-Times, the SIS have been asking local Algerian refugees about Ahmed Zaoui, turning up unannounced on their doorsteps and conducting lengthy and intimidating interrogations. The refugees must have felt right at home - especially when the agents identified themselves as "mukhabarat". Isn't this sort of thing exactly what they came here to escape?
From the sound of it, the SIS are desperate. They know their "evidence" won't survive even cursory investigation, even by a patsy like the Inspector-General, and so they're desperately trying to dig up something - anything - to justify their decision. Shouldn't they have done that before having someone imprisoned for two years?
