I’m not convinced that these people are organized and competent enough to kill people in that scale without people finding out.

Same thoughts. But also too incompetent to single out the detainees who won’t ve missed.

That said, I am certain that a whole lot if people have been killed in custody and covered up, but I don’t think it’s on a scale like that.

Oh for sure, but it’ll again be at least part Incompetence and part maliciousness, with an unfortunate outcome.
