Bat in hand, the bowler advances

Shoaib Akhtar works hard to make sure that the leading contender for, er, leading the Pakistani pace attack can't even run. This incident raises a few questions. To wit:

1. Were both Asif and Akhtar off their medications, or was it only one of them?
   
2. Could this be a hit ordered by a dealer?
   
3. Have medical practitioners checked in to see if their case provides any interesting insights into withdrawal symptoms from nandrolone?
   
4. And lastly, what is it with Pakistani cricketers and the urge to assault with a cricket bat?
