The BuzzFeed articles don't show hardly any current pictures of the camps. And it doesn't seem that hard to believe that the detainees would most of the time remain indoors being de-radicalized and re-educated. The guards would be in the towers, or in the buildings, or looking at the camera feeds. I'm sure that people with better images than the few we saw here are working to figure out exactly what's going on in these camps and as best as possible following all the logistics. At least I'd hope so as China is being very secretive about them.

The authors and their teams clearly took into consideration that these could be military bases and they talk about it to some extant. I'm sure it could still be the case that some of these are barracks and the Chinese make their barracks look like detention centers. Some of the locations they found have been verified by other sources though.

We also have that drone footage of detainees being transported, right?

Also, the leaked document from the NYTimes talked an awful lot about security, not letting people escape, and not letting images or information of the camps be leaked for a normal vocational school.

The Wuhan hospital parking lot study was pretty bad, but worse things have come out of Harvard Medical School in recent months.
