Seems to me that this would be a huge opportunity for some well co-ordinated use of social media by the MET: many people have seen looters return to their home with their swag and would probably be delighted to report it anonymously - along with all photos taken by people of the actual looting. The refugees seem to have no clear contact number let alone website to go to on their smartphones. These people surely are motivated to inform on the rioters and quite probably have useful knowledge. And finally, phone location records - even without call history and text messages - could be data-mined to give leads on the rioters - when they go home to sleep pick them up with the loot, and you have an easier case than two weeks later with it all squirrelled away.
