Mexican gangs threaten school teachers
If the government isn't behind this then at least it's responsible for its prevention. Are gangsters stupid enough to target teachers? Shouldn't they try to extort from high-income people? The Mexican teachers' unions have been the backbone of resistance to the criminal regime in Mexico City. A coincidence? Maybe. Maybe not.
