> Now the evidence itself suggested at least a plausible hypothesis: the attacks were triggered when a bus used to transport heroin was commandeered by the students, and that the motive—because the municipal police and others involved in the attacks didn’t know which of the commandeered buses had the drugs aboard, or perhaps had been specially outfitted to smuggle drugs without detection

That's a very plausible theory. I wonder how much drugs could a bust like that carry.
