Who cut the dam?
With three very divergent view points, one can only conclude that while the BNP contractors were fighting over each other as to who would do the work, and the WDB officials awaiting the result of their fight as uninterested party, the water broke through and washed away any evidence of sabotage or any other cause of the incident.
Poor WDB officials are now left behind as the easy target. They unfortunately may have no choice between the frying pan and the fire. No wonder governance in Bangladesh is going away fast, like the flood waters; also flushing out all the contradiction between different agencies and leaving the unfortunate officials on the spot sucked into the mire caused by others' misdeeds.
