7. The Cowl-Cam
In recent adventures, Batmans mask has been depicted as containing a built-in camera, recording evidence that The Batman can examine later, without the annoyance that comes as a natural consequence of lots of people trying to shoot him all the time. Recently, Batman employed this technology to determine that Maxie Zeus was relaying a Morse code message with his eyelids (Haunted Arkham) and to grieve over the loss of his son, Damian (Nowhere Man). This is a relatively new technology in the Bat-Books, but it's safe to assume that the restlessly inventive Dark Knight has been developing it for some time. It is also reasonable to assume that Batman may turn some of the videos over to the Gotham City Police Department as evidence of crimes being committed, because simply tying the culprits up with a bat rope and leaving them hanging from a lamp post is surely not admissible in court these days. Having said that, because Batman said so would work very well for me, were I in the jury.
