Well the authorities are fully responsible and the ones to be blamed for watching this things happen again and again. Why dont they act and put in place some punitive laws whether the guilty are locals or foreigners so that this crimes against poor and helpless workers are stopped once and for all. Its such a shame for countries to be associated with this types of crimes against the weak and the helpless people. They come here to make a living but they never get back home where their family waits for them
