A similar technique was used to identify suspects in the 2011 Stanley Cup Riot in Vancouver, Canada.[0] With people using the footage and pictures of the riot and submitting identities to the police. I'd be interested in seeing similar techniques used else where. It seems to have worked extremely well in the case of this specific riot.

This thread reminds me of the "hunt for things on Mars" online tools https://www.zooniverse.org/project/planet_four.

You could basically tag all the specified features in images (in this case it would be faces, bags) and add special comments if you thought you saw something special (a person you recognised, a bag make, an apparent clue).

That would crowdsource the facial/bag recognition and identification aspects without giving scope for trial-by-webapp.
