Meet Charles Moore. The Arkansas man, 25, was sentenced last month to 20 years in prison for a December 2004 motel stickup and his subsequent assault of a jail guard. While in custody a few months back, Moore decided to add a tattoo to his already impressive collection, which includes lightning bolts, a dragon, a marijuana leaf, and a joker. Employing a primitive jailhouse inking process, Moore placed a two-word message on his forehead, a greeting that he apparently sought to permanently extend to law enforcement officials, according to a recent story by John Lynch of the Arkansas Democrat-Gazette. Moore's new tattoo was quickly added to the inventory maintained by the state's Department of Corrections.
