Am I the first one to see this won't work?

Now, in order to stop 'em in their tracks, we'll have 'em tell us their social media accounts.

I sure hope that none of the bad guys/gals have multiple or hidden social media accounts. Or fake accounts..... Why do I think that this is not going to work while at the same time lessen the privacy of just about everyone? If they want to know who is doing what on Facebook, my opinion is to start waterboarding Mark Z. to give up the security codes to the Facebook domain.
