Polri is the national police of Indonesia. The photo was taken in early September 1999 near Viqueque, East Timor.
A few days later on the 7th of September I had the pleasure of attending a shooting incident against the UN HQ building in Baucau. I was in the building when a Militia member entered the building and cocked his weapon right in front of me. Afterwards the building was surrounded by Timorese Militia (Aitarak or MILISI) and Indonesian Police (POLRI) who proceeded to shoot into the building at waist level through the windows. A rather uncomfortable hour or so was spent lying on the floor watching bullets make tiny holes in the walls around me. One estimate was that 4000 rounds were fired.
This was rather intimidating and I suffered a loss of high frequency hearing as a result of the barrage and I remember thinking what on earth I was doing there. Ten days later I was among the first to return to East Timor and I am still wondering what was I thinking?
