Vigilantes have killed at least 164 people since the movement dubbed “bwa kale” began in April, according to the United Nations. The name means “peeled wood” in Haitian Creole and insinuates male dominance and power in street slang.

“If you’re not from here, we’re going to kill you,” said Leo, a community leader who granted the AP access to the Turgeau neighborhood so that journalists could see how the neighborhood is responding to the gangs estimated to control 80% of Port-au-Prince. He did not provide his last name to protect his family.

Banners that read, “We are tired of the kidnapping,” and “Watch out for one another,” are strung throughout the city, and many neighborhoods have erected barricades like those closing off Turgeau.

On a recent afternoon, Leo and neighbors guarded one of the four makeshift barriers blocking roads into their hilly community of doctors, nurses, pastors, lawyers, street vendors and engineers.

People who wanted to enter had to show their IDs, open their bags, lift their shirts to reveal any gang tattoos, and, if they didn’t live there, explain where they were going. At night, those seeking to enter Turgeau also had to provide a password, which the community changes every week.

Haitian police don’t keep reliable crime statistics. But gang-related killings and kidnappings have dropped because of bwa kale, say human-rights activists, who also worry about the gruesome violence, and that innocent people could be killed.

Weslander Al Cégaire, a cook in the southern city of Les Cayes with a round face and easy smile, told the AP that his cousin was recently killed by bwa kale participants while riding with a motorcycle driver who was targeted.
