They already do, If torturing a terrorist for information saves hundreds of lives so be it. What other method of extraction can you think of?? free meals and holidays for life for any information given??
I know, that is why I said 'will feel justified'! One thing is for sure, we have no clue whether or not physical torture of suspected terrorists will achieve anything. It's 2017 - we now have effective ways to obtain information without waterboarding,etc. There's plenty of material out there via google, for example.
