Green Lantern: Emerald Dawn II #1 (1991)

Hal Jordan appears in court to take responsibility for the accident he caused while driving under the influence of alcohol. Unfortunately, the judge makes an example of him, and sentences Hal to 90 days in a maximum security facility. After one last visit from Carol Ferris, Hal is hauled away in a prison truck. However, when he hears about a crime over the police radio, Hal activates his Green Lantern Ring, leaving a projection of himself behind, and then patrolling as Green Lantern, hoping to be back before anyone notices that he's missing. As Green Lantern, Hal stops a robbery at a savings and loan. He does well, until one of the robbers hits him with something yellow, reminding him of his weakness. He manages to subdue them, building an enclosure for them out of the linoleum flooring. Then he activates the silent alarm, and escapes before the police arrive. He manages to get back into the truck without being noticed, just as it arrives at the state prison. When Hal is being processed, an officer asks him to remove his ring, and using sleight of hand, he makes the ring disappear. Unfortunately, this annoys the officer, and Hal is ordered to undergo a strip search - but he manages to keep his ring, nevertheless. In his cell, Hal is frustrated as he is forced to sit through a threatening tirade by his cellmate without using his ring. Strangely, the speech is cut short when his cellmate is stabbed in the back with a shiv. Of course, Hal becomes the prime suspect, and is forced to undergo questioning. Eventually, he is visited by his case worker, Guy Gardner, who hopes to help Hal out of the situation. On Oa, the Guardians of the Universe bemoan Hal's lack of training, knowing that Kilowog is occupied by recruitment duties. As a replacement trainer, they select Sinestro, who keeps a tight control over his Sector 1417. Sinestro, meanwhile, seems to keep a more tense and perhaps somewhat superfluous control over his sector, requiring celebrations every time he visits its planets. Even so, he is summoned before the Guardians, and given his assignment. Despite his displeasure, Sinestro views it as an opportunity to train someone to keep his style of order. As Hal struggles with his commitment to serve his time without using the ring, he is suddenly surprised by Sinestro's appearance, and Sinestro is none too pleased himself.
