(smiling photos at link) http://www.palmbeachpost.com/news/c...ty-whats-so-705427.html?cxntlid=cmg_cntnt_rss For most people, it's the worst day of their lives. Most arrestees are pretty sullen. They were caught driving drunk or they just beat someone up. Some are hung over, dirty and bruised. Then there are a handful of arrestees at jails across the country who every day flash toothy grins for their mug shots - one last hurrah before lockup. Stephen Holmes, associate professor of criminal justice at the University of Central Florida, thinks grinning inmates are thumbing their noses at the criminal-justice system. "You see this with people who have been in and out of jail a lot. They think it's a joke," Holmes said. "It's an affront to the system because this is the picture that is going to follow them and they know people will see them smiling." While jail officials don't find the humor in a smiling inmate's booking photo, the happy mug shots are an entertaining diversion for the public and a corrections phenomenon. Viewing booking photos has become an increasingly popular pastime in recent years with the growth of the Internet and explosion in digital photography. In states like Florida, where mug shots are public records, law-enforcement agencies often make the images easy to find online. There's an appetite for the photos, especially ones of jubilant inmates. "It's basically voyeurism and taking pleasure from someone else's misfortunes." The Cheshire Cat smile on the mug shot of former Republican House Majority leader Tom DeLay went viral after his 2005 arrest. Some Central Florida media poked fun at state Sen. Gary Siplin's flashy grin in a booking photo after his arrest in 2006. Recently, Larry Jason Wonn, 22, of Casselberry, gave a big smile at Orange County when he was booked on charges of possession of marijuana, possession of drug paraphernalia and driving under the influence. So did Mariluz Rosa, 37, of Orlando, who mugged it up when she was booked on charges of aggravated assault and battery. Both their cases are still open, according to Orange County Court records. But why are they grinning? "Alcohol and drugs are usually to blame. Some (arrestees) come in here intoxicated on alcohol or under the influence of drugs and don't really know what's happening."
