No, it does not.

There's a guy from Lebanon who ended up moving to Germany called Khaled El-Masri who got seized in Macedonia by the US and who got sent around a bunch of US black sites.

Eventually people figured out he wasn't Khalid Al-Masri and started treating him better, but he still almost died. Consequently, the people who weren't treated better almost certainly did.

This can't really be disputed. The US certainly killed people at these black sites. The obvious danger El-Masri was in makes that clear.

There is a screw-up in my previous comment since I say Poland rather than Macedonia or Afghanistan, but there's reason to think that the Polish black site is iffier than the others because of how the investigation of the location was performed.
