On Friday, an operation by Brazilian military police in Rio de Janeiro left at least 13 people dead after a shootout in the neighborhood of Santa Teresa. Police say they were there to investigate suspected drug traffickers but encountered gunfire when they entered the area. This comes after Rio’s new governor, Wilson Witzel, said last month that city security forces were authorized to shoot to kill suspects. He also said Rio should have its own Guantánamo Bay to house criminals, whom he labeled “terrorists.”
