when you have graffiti materials they always assume you "planned it out" if they haven't already caught you in the act. they NEED reason to search you and if they can't they won't find it on me and if they do and ask you have the right to keep quiet no matter what they say. if they persist: caselaw.lp.findlaw.com/data/constitution/amendment05/. though, most cops are "above the law" and say that doesn't apply...but OF COURSE IT DOES!
do a handstyle or simple character on the adhesive side of a sticker and slap it on the inside glass of a newspaper dispenser, it'll last 100x longer than something on the outside and, unlike putting a sticker on the display holder which gets covered up when they restock the magazines/newspapers, it is visible over the front display
