One of the things that brought me back to thinking about crime and fashion was the publication of the FBI gang threat assessment. It addresses their research findings and perspective on organized groups throughout the U.S. and frequently throught the brief it discusses dress.
There has been some blowback as some groups feel they have been unfairly characterized as a criminal gang based on subcultural appearance. Others have agreed that the symbols they present do represent a life of crime and partake in activities such as laser removal of particular tattoos. Give the briefing a scan as its a very interesting document.
