Better than waterboarding!!!
 

If it works, is effective in getting good intel and is safer than waterboarding, go for it!

Tickling feet with a feather also works. If it worked so well all the time everyone would have used it. I am very sure India is a lot less careful of what it does with people like this....

Couple of grammes of pure MDMA would do the trick too. The little ***ck would probably want hugs though.
