Anonymity in Crowds

Join the Guinness Book of World records here! 2011 Stanley Cup Game 7, Vancouver, Georgia St

So let me get this straight. They are asking people to identify themselves (and probably others) on a composite image taken before (?) Game 7 in Vancouver. The same area that went on to riot. Does anyone else wonder that maybe the cops or investigators might pour themselves through every last pixel of information on those pictures to see if they can't pick out people they identify from riot footage?

Ha! Where's your Fifth Amendment now? (yes, I realize it's Canada, not the US, but Canada still has laws against self-incrimination, so it still applies - kinda)

Do we have a provision for that in either Constitutions? If you identify a picture of yourself on the internet, and it gets to a cop, and the cop uses that to ID you from other footage of you committing a crime, is it fair game in court?

A great example of how privacy, law,and the internet have collided to make situations like these still a little nerve-wracking. Have some foresight before you blindly tag yourself on someone else's attempt at the Guinness Book of World Records.

Oh, I haven't asked, but does the website allow you to petition to shop out your picture if you so desire? Hmm. Lots of issues here.
