Protesters in the Mexican state of Guerrero have set fire to the local legislature as outrage spreads over the disappearance of 43 students. The students from Ayotzinapa teacher’s college have been missing for nearly seven weeks after they were ambushed by police. Unrest has intensified since Mexican Attorney General Jesús Murillo Karam announced Friday that suspects in the case have admitted to killing the students and incinerating their bodies at a trash dump. More than 70 people have been arrested in the case, including the mayor of Iguala, who is accused of ordering the police attack. Across Mexico, tens of thousands of people have taken to the streets in peaceful protests, while groups of demonstrators have laid siege to government buildings, burned cars and blocked highways. The parents of the missing students, meanwhile, have announced they will be traveling across parts of Mexico in three caravans to demand their loved ones’ return. We are joined from Chilpancingo, the capital of Guerrero state, by John Gibler, an author and independent journalist. “I don’t think it’s possible anymore to talk about corruption,” Gibler says. “What we have is two sectors of an industry that have fully merged — the police and the organized crime gangs themselves.”
