In my eighteen years here in Cambodia, I have never seen a fire truck fighting a fire. In fact, I have only seen a fire truck on the street four or five times. I read in the paper that they occasionally do go to fires but usually part of the story is that they don’t actually do anything until the firefighters are paid on the spot.
Today I heard fire truck sirens four times and actually saw this one! All this activity probably means the government is getting ready to use the fire trucks against demonstrators. National elections are coming up in July and the trucks are probably part of the intimidation of free speech in the run up to the voting.
