Green Lantern, Vol. 2

"The World Of Perilous Traps" - Hal's power ring seems to be malfunctioning, missing targets and accidentally harming friends. In a bout of frustration, Hal throws it away, only to learn that he's fallen into Sinestro's trap.

"Green Lantern vs. Power Ring!" - Hal realizes there is still much he doesn't know about his power ring. He and Pieface head out to the wilderness to test it. When trying to determine the range of his mental control over the ring, he goes far enough away for a homeless criminal to find and take the ring, and use it for revenge on the society he blames for his ills.
