Candle holders keep protest banners in place during a demonstration demanding better security following a deadly arson assault, in Monterrey, Mexico, Friday Aug. 26, 2011. A surveillance tape showed eight or nine men arriving in four cars Thursday at Monterrey's Casino Royale and setting fire to the building; trapping dozens of people inside and killing at least 52 people. The attack was different than others in recent years in that the victims weren't cartel foot soldiers or migrants resisting forced recruitment by gangs. They were part of the middle class, working or gambling in an affluent part of a city that was once considered one of Mexico's safest. (AP Photo/Arnulfo Franco) less
