Here we have Hal Jordan (a.k.a. Green Lantern) stuck in jail for one of many times in his history. Obviously, in this case, Hal must have a private cell, and from the look of things, he's putting the privacy and idle time to good use. Maybe this is merely an example of poor hand placement, but it would also appear that Hal's, er, RING hand certainly isn't being, er, idle, either:
Not only that, he's using the power ring to probe the minds of the people around him. Probably looking for dirty pictures to project onto the wall of his cell. Shame, shame, Mr. Jordan!
