The very reason why CBI was asked to take over the case of Noida double murder was mess up by UP police. Now after a month CBI's spokesperson mentioning that UP police did not do their job well is mockery of themselves. Yes there cannot be magical solutions for every problem. It may take months to investigate. Let them tell that, rather than pointing finger at someone/some agency whose improper homework has brought CBI. CBI was brought in to plug those loopholes and not to just tell there are loopholes.
