Someone on the radio earlier from the US was saying it could take them a while to get through all the evidence they have. By that he meant everyone pretty much has a phone with a camera, it was televised, cctv, pictures from people at event. All has to be checked thoroughly and could take time.
My question is in such an event do you think if they collected together everything they had and posted them up on a domain for people to view then the 'internet' could help? Not quite on the same level but some of the detective work on here is impressive at times and if you through enough people at something they can surely help spot something that maybe be missed. Huge amount of people on 4chan/reddit/something awful etc.. all these resources pooled could help make the work much easier.
