Fictitious until some Dexter copycat killer comes along. Nener Nener!Worth mentioning, people do share too much. A great fictitious example may be found on "Dexter." The Trinity Killer used a minivan with a stick figure family on the rear window to identify his next victim. Fictitious, yes however think about the information one can learn about you personally. Automotive parts stickers are kewl, but all they say is what's under the hood of your car. Next time you walk through a parking lot look at the vehicles of those who are potential future victims.
