People ought to start saving the photos now. I'm sure they'll produce some suspects eventually, but I won't be shocked if they end up being individuals that were no where near Boston when this occurred. Everyone by now knows how essential the first 24-48 hours are of an investigation. After days it'll be easier to point fingers at people across the country. Maybe even swoop up a group of people claiming it's a conspiracy.
Of course, if I were a crooked sob I'd do it that way. In fact I'd create a false group, organization, cell, etc. that I could blame a number of the bad things happening on. They could make Boston, Texas, and the sabotage events in Cali all appear to be a joint operation trying to destabilize government.

Guess we just have to wait and see.
