I remember when multiple school busses of students went missing and it turned out the Mexican military thought they were rivals of the local cartel pretending to be students, so they handed the busses over to said cartel. Who immediately murdered everyone on board, then hid the bodies and the vehicles after they realized they fucked up and killed a bunch of innocent students.

The cartels are capital-E Evil to a degree most people can’t conceptualize, and the authorities are hopelessly corrupt and openly assist them.
