The suspect, described as a "high value target", was being interrogated by a member of the special forces unit specially trained in "tactical questioning", with a British military interpreter and an Afghan interpreter present.
Nice use of quotation marks to add speculation to fact for a better story, but they forgot to put the word "suspect" in quotes as well. If you have no legal due process for getting from "suspect" to "convicted" other than torture and interrogation, you are on a very slippery slope. Kangaroo courts, despotic dictators, random milita that shoot civilians on sight - let's make sure these are all things that happen in third world countries or totalitarian regimes.
