On Friday, thousands of protesters will converge on Fort Benning, Georgia, home to the Western Hemisphere Institute for Security Co-operation (WHINSEC). It’s had this title since 2001, but when it was set up in Panama in 1946 it was the School of the Americas. In 66 years it has trained 64,000 soldiers from Latin America in counterinsurgency, sniper warfare, interrogation techniques and other useful methods for repressing their citizens.
