One article discusses the high cost of replacing glass that has been etched with graffiti applied with rocks, sandpaper, steel wool, drill bits, machinist scribers, composition shingles, or sharpened metal. It notes that recent research connects the increase in glass etching to restrictive access laws that pertain to aerosol spray cans and wide-tip markers. Another article reports on successful tests of transparent films applied to windows to prevent shattering in attempted "smash and grab" burglaries. A third article criticizes California bill 839, passed October 1, 1993, which authorizes the furnishing of aerosol containers of paint or other related substances for use in school- related activities when used under supervised situations. The author believes this undermines the effect of existing law that prohibits anyone but parents, legal guardians, or employers from providing aerosol spray cans to a minor. Other articles pertain to the selection of a graffiti removal product, the identification of graffiti writers from graffiti they have written on their own vehicles, a new paintstick used by graffiti writers that "bleeds" through successive layers of paint, vandals' use of pellet guns, alphabet variations adopted by cults and gangs, and documenting and photographing as the key to the graffiti problem.
