Protests in Mexico Over Missing Students

It's been more than a month since 43 college students went missing in Mexico, and their families still have no answers. As they grow impatient with authorities, protests have broken out and gone as far as burning Iguala's City Hall. The mayor of that city was arrested, along with his wife and many others, in connection to the crime. But besides that, there's been little progress in the case.
