Note from Commissioner James Gordon:

This disc is a GPD-mandated record of events leading up to the July 18, 2008 bank robbery that set off that year's period of terrorism perpetrated by the Joker. Within, you will find investigation overviews, suspect dossiers, website records, physical evidence details, and the undoubtedly disturbing story of a psychopath who was able to gather a mind-boggling number of followers (approximately 10 million individuals participated) who aided him on his streak of terror. We must learn from this so it can never happen again.

GPD was able to thoroughly investigate these events by using information in a public "Wiki" organized by the conspirators themselves.

Needless to say, this information is extremely sensitive and possibly harmful. It should not be disseminated outside of MCU headquarters UNDER ANY CIRCUMSTANCES.

Best regards,

James Gordon
