The 'Justice' Department’s strategy in the trial itself, using a seldom-tested conspiracy law and relatively thin evidence, cemented a new prosecutorial model in terrorism cases. The central charge against Mr. Padilla was that he conspired to murder, maim and kidnap people in a foreign country. (...)
But prosecutors needed to prove very little by way of concrete conduct to obtain a conviction under the law. "It is a pretty big leap between a mere indication of desire to attend a camp and a crystallized desire to kill, maim and kidnap," said Peter S. Margulies, a law professor at Roger Williams University who has also written on conspiracy charges in terrorism prosecutions.
The conspiracy charge against Mr. Padilla, Professor Margulies continued, "is highly amorphous, and it basically allows someone to be found guilty for something that is one step away from a thought crime."http://www.nytimes.com/2007/08/18/us/nationalspecial3/18legal.html?_r=5&oref=slogin&oref=slogin&oref=slogin&oref=slogin&oref=login
