To students: 45th Anniversary of the Tlatelolco Massacre

Today marks the 45th anniversary of the massacre. This YouTube video captures the basics of the massacre, but I think it's important for students in particular to take a look at this.
I think it's important to show students how people banded together to fight for a proper education system.
Even though the protests ended in a massacre, the people's determination for change is what should be remembered as well.
