As this unfolds, worth noting that Khashoggi was I believe 59, portly. Pretty hard to see how an interrogation could have led to his accidental death. Torture, maybe. But again, a police or military team can pretty easily take custody of someone w/o killing them.
Yep. Even if he resisted, they'd have to have been pretty incompetent not to be able to subdue him without killing him if it were't their intent all along to kill him.
