I've got an idea that'd help us find these rotten rioting shits.

We've got thousands of pictures of them from CCTV, camera phones, news footage. All we need to do is connect those images to Facebook. It'd need a fairly chunky Facebook Graph app, and some face matching software.

Here's how it'd work:

• We have a library of photos (criminals)
• I connect my Facebook account to the app
• The app scans my friend list, grabs a profile image for each, and tries to match it against the library of bad slags
• If it doesn't find any in my immediate network, it starts to crawl my friend's public walls, searching for shitty crims
• As soon as it gets a match it flags it as a potential convict 
• It uses the matched profiles as seed points to continue crawling

You can assume that each robbing dickbag is associated to other robbing dickbags through a couple of degrees of separation on Facebook, so a couple of matches would unlock thousands of others.

Here's what it'd take:

• Lots of crunching power
• Something that'd match faces (maybe Picasa?)

Who's in?
