may take still or moving images of the defendant, and often ask questions of him or her. In high-profile cases, with major media interest, such as a crime which has received considerable public attention or in which the defendant is a celebrity, measures such as barricades or extra uniformed officers will be present to ensure there is space to get the defendant and escorting officers into the building. "You naturally assume you're seeing a barbaric mob wreaking random havoc," writes New York Times columnist John Tierney of such scenes. "But that's not the case. It's actually a barbaric mob wreaking exquisitely planned havoc." Defendants Most law enforcement agencies will allow suspects to temporarily hide their faces during their perp walks. They may simply (if they are cuffed in the front or not cuffed at all) use their hands to shield their faces from onlookers and the press. Some may wear sunglasses, and some may wear hooded shirts or jackets that they then wrap tightly around their faces. Suspects sometimes pull clothing over their heads or walk with their heads down to hide their faces. Suspects also often struggle to walk and hide their faces at the same time as they are often bombarded with the microphones and cameras of the press covering their arraignments or cases. The police also sometimes provide certain defendants, such as accused current or former police officers and criminals who have been useful to them as informants, with hoods and abbreviated perp walks from a side entrance. Conversely, in a high-profile case, the police may accommodate the media by extending the perp walk into a "perp parade" beyond the necessary distance, such as around the block, or delaying the court proceeding until the media can be present, as was the case at the 1999 arraignment of former Wu-tang Clan rapper Russell Jones on charges that were later dropped. Perp walks were restaged for the benefit of the media until a 2000 court ruling restricted them to those necessary for law enforcement purposes. Defendants who can anticipate their arrest often dress with the perp walk in mind. Two former federal prosecutors turned defense attorneys advise that a white-collar defendant "should be prepared to look as professional as possible under the circumstances," as the fictional character Sherman McCoy does after he surrenders to face a charge stemming from a hit-and-run accident in Tom Wolfe's 1987 novel The Bonfire
