How can a crew brilliant enough to pull off this million $$$ heist by disabling sophisticated alarms be stupid enough to send pictures of the stolen items to investigators with the EXIF intact?
Just goes to prove that there really is no such thing as a criminal mastermind.
Not really ... just that there are a lot of criminal mastermind wannabes. If there were really a "criminal mastermind" out there we -- by definition -- wouldn't know. I hate to quote Donald Rumsfeld, but an absence of evidence is not evidence of absence ... :-(
An art thief this sophisticated doesn't own a stolen camera to take photos?
Part of this rings of they didn't get the thief but instead got some idiot that the thieves either stole the artwork for or sold it to. The photos and the email were a way of trying to anonymously check if the coast was clear to move them.
