There is one glaring omission in this story and others like it. It is frustrating and angering and... GGGGRRRRRrrrrrrrrr!
How can 200 hostages be liberated without finding and killing any of the killers involved?
How much infrastructure is necessary to kidnap and hold that many policemen?
My gut feeling is several times that "200" figure.
Without killing the rats, the kidnappings and murders will continue forever!
