Also the "we can get you organs in a day, give us the specific requirements..." is a pretty serious red flag even if there's a high normal donation rate.
Yes, I would agree there. Though that might also be a sign of an opt-out donor policy.
Also, the particular crime charged here is that not only are organs harvested from prisoners / execution victims, but prisoners are specifically killed in order to harvest their organs, including a pre-execution check for histocompatibility.
There is a distinction to be made between small scale criminal behavior on the part of the hospitals and prisons, and a large-scale state-sanctioned practice of illicit organ harvesting.
