A public service announcement: If you have a large stash of naked pictures of yourself, do something productive with them. Take up erotic scrapbooking. Make some pornogami. Give your cockatiel the swingingest bird-pad in Idaho. If all else fails, dump them in a bin and give the guy down at the recycling plant a story to regale his friends with. But don't throw your pictures at children. Franklin Arroues, 45, of Boise was arrested last Wednesday and charged with doing just that, in the area of Edna and Maple Grove on March 31. Understatement of the week: Witnesses were able to provide a "detailed" description of both the suspect and his automobile, according to a Boise Police Department release.
