Homeland Security Making "Minority Report" a Reality

You remember the 2002 Tom Cruise film, Minority Report, right? In that movie, the government had a PreCrime Department that stopped crimes before they happened. Well, Department of Homeland Security currently has a program to do the same thing.

From Wired:

The [Department of Homeland Security] is already testing a program on select members of the public to determine if algorithms using these factors could indicate mal-intent, according to an internal document obtained by the Electronic Privacy Information Center and passed to CNET.

...

FAST is designed to track and monitor body movements, voice-pitch and rhythm changes, eye movement, body heat, breathing patterns, blink rate and pupil variation.

So the question is, if you demonstrate certain physiological traits that have been determined by the government to indicate that you are about to commit a crime, would that be considered enough probable cause of your alleged intent to commit the crime to detain you?
