Davids 'crime'? - wearing a rucksack along with an 'unseasonal' jacket and checking his phone messages while waiting for his train. Luckly for David the police refrained from following the shoot-to-kill policy that had resulted in the tragic death of Jean Charles De Menezes less than a week earlier. Instead, they closed Southwark tube station and cordoned off the whole area while the bomb squad checked his bag. Eventually, finding nothing but a laptop in his bag, the orginal officers appologised then arrested anyway. His home was searched and his computers confiscated. You could be next.
