Looking at the facts...
1) He is in charge of the worlds largest terrorist organisation.
2) He is apparently living in a cave in afghanistan
3) He runs the entire operation from a mobile phone
I have the following question...
"WHAT NETWORK IS HE ON?!?!?!" I'm sat at home trying to text a friend and i cant get a signal when the transmitter is just up my road, yet osama deep inside an afghani cave can talk to the friggin world...!!
Secondly! Where does he buy his top up cards? He cant be on a contract or we'd have his address!!! C'mon people!
