The mining companies usually hire military and paramilitary personnel to be their security forces. So when these abuses are committed, the mining companies are involved directly or indirectly.
Cases have been filed in the local courts but no actions have been taken. Cases have even been filed by the commission on human rights against the military forces with the Southern Command--the armed forces of the Philippines--but still no action has been taken. So there is a connection in the sense that the mining companies have hired these military personnel to be their security forces.
