Agree. Also, if you’re heavily armed & outnumber your opponent, you storm the building and go room by room searching if your goal is to kidnap . You don’t set fire to the building as your 1st act, unless your goal is to kill him.
Supposedly the guys who were supposed to just kidnap Stevens were replaced by jihadis who caught wind of the plan.
The idea was to say that Stevens was kidnapped as a result of the video.
