absolutely. new trend in absolving rich and powerful owners. first ploy destroy evidence. next, make the case difficult to solve. and conveniently blame it on servants. its always there. ask any rich family, the condition under which a driver is kept - in case of an accident, the driver has to own up under any circumstance to protect the owner!
well, the cops have taken this to another level. when it was so clear that the cops were botching it up - why dont the cops get docked for covering up the case or destroying evidence ?
