CLEAN: FARC guerillas on trial in indigenous villages

The NASA people of Southern Columbia, caught between the army and FARC guerrillas, have decided to administer justice according to their own laws. They captured four FARC members and held a trial in their native language, with local governors acting as judges. The trial ended with a guilty verdict and a sentence of 30 lashes each. The community is aware that these actions may lead to reprisals from the FARC.

What concerns do the indigenous people have regarding the trials they conduct?
