Anderton's Pre-Crime clearance
Is such a HUGE plot hole.
In Minority Report, technology and identification are driving forces of society. So how does an agency like Pre-Crime make the mistake of not revoking Anderton's clearance? Then to make matters worse, they don't learn from their mistake after Anderton kidnaps Agatha. Lara is still able to gain access using it later on. As much as I love the movie, the clearance issue has always really bothered me.
