What Happens in Vegas Stays in Vegas

If Las Vegas is the City of Lights, then why is it so hard to see the human sex trafficking taking place on the strip? There is probably no city in America where women are treated worse than in Las Vegas. The tone of systematic, institutionalized degredation is set by the mayor, Oscar Goodman, who said in an interview that the city would reap "tremendous" benefits if a series of "magnificent brothels" could be established to cater to johns from across the country and across the world.  Las Vegas is with out a doubt, as psychologist and researched Melissa Farley, says, "the epicenter of North American prostitution and sex trafficking." I have been to Las Vegas and it is evident that sex is all around you. You can be waiting to cross the street and a huge mobile bilboard will drive by saying "Girls to your roome in 20 minutes". There are also countless men standing on the corner of streets handing out cards selling nude women. If prostitution is illegal in Las Vegas than why does the city not take any action in stopping these illegal functions that are so obvious. Making Vegas a world class embarrassment to any U.S. official attempting to reduce prostitution and trafficking in foreign countries. Why are we so focused on stopping it in other countries when we cant even stop it on U.S soil first?
