I Agree. It's Brietta who prefers the emotive description of 'interrogation' that Kate went through. I think it was an interview. In an interview room. Amaral called it an 'interrogation', which I believe is merely translatory language.
Murat, although clearly unimpressed with his treatment, as you'd expect when one is being fitted up, he never said he was interrogated
interrogation/ɪnˌtɛrəˈɡeɪʃ(ə)n/

the action of interrogating or the process of being interrogated.

My use in a post some time ago, of the word "interrogation" appears to have become a bit of a cause célèbre which is quite flattering when you think about it ... but what is singularly amusing is that derision of translation errors in the files transmogrifies into claims of translation errors where Amaral is concerned.
