El Salvador’s Centro de Confinamiento del Terrorismo (CECOT) opened in 2023. It has capacity for up to forty thousand prisoners, although is said to be only half full. CECOT was built to incarcerate members of violent gangs, who by 2015 had made El Salvador the Western Hemisphere’s most dangerous country. Dispensing with warrants and court hearings, in 2022 the government jailed almost 2 per cent of the population, many on the basis only of their tattoos. The official murder rate fell from 18 per day to one every three days. In early February, Trump’s secretary of state, Marco Rubio, toured Central American capitals. In San Salvador, President Nayib Bukele, who calls himself the ‘world’s coolest dictator’, offered to make his prisons available, for a fee, to hold ‘criminal’ migrants deported from the US.
