A corrupt politician who is paying a spy to get info, can pay the spy to also get info useful to alQ. I would imagine that alQ would pay enough for certain info for the politician to turn a profit. Are you saying a Philippine politician would turn down extra cash?
No, he would not turn down extra cash, but he wouldn't be stupid either.
The problem is that thats not the way things are done there. One deals with relatives for safety, thats the SOP. Nobody important in Phil politics has that sort of family connection.
This was high-level info handed over to high level people, they would not implicate themselves through risky contacts.
