Re: BB Messenger vs BES
In either case, what the ISIL Sponsors Incorporated (abbreviate it yourself) want is all keys to decrypt themselves instead of a case by case basis.
That is a non-starter as it will allow them to snoop on BB communications outside the territorial boundaries of Pakistan. Their need for it is clearly understandable as it will provide them with an early warning so they are not surprised by midnight raids to execute international terrorists they are hiding inside Pakistan. I do not see why we should cater for this need.
