My (albeit brief) experience with Thai police investigation scenes is that if something goes missing, it was most likely the Plod that nicked it. In August, an unfortunate resident of my condo building passed in his sleep. When he was discovered four days later, the BiB were called and insisted that the building management stay outside while they "searched" his room. Family later reported cash and Rolex watches missing. When the rescue foundation arrived to remove his mortal remains, they nicked all the grog.
