<p>The Good Samaritan may soon be extinct in Thailand if the police response to a recent road traffic accident becomes the norm.</p> <p>It all started with a run of the mill hit-and-run. A tinted-window Mercedes (is there any other kind?) side-swiped a bicycle that was dutifully trundling along in the gutter, bringing down both rider and machine. Nothing life-threatening and the bike was damaged but repairable.</p> <p>Not that the Merc driver knew. He was long gone.</p>
