The news that US citizen Jose Padilla has received a prison sentence of 17 years and four months should provoke outrage in the United States, although it is unlikely that there will be much more than a whimper of dissent.

The former gang member and convert to Islam -- whose arrest in May 2002 was trumpeted by then-Attorney General John Ashcroft as that of a "known terrorist," who was "exploring a plan" to detonate a radioactive "dirty bomb" in a US city -- was once regarded as one of the most dangerous terrorists ever apprehended on American soil. Almost six years later, as he received his sentence, he was not actually accused of lifting a finger to harm even a single US citizen.
