The argument that organs would be thrown away otherwise doesn’t justify bypassing clearly defined consent and ethical standards.
Was this unethical? Yes. Is it the darkly hinted about conspiracy to procure black-market organs some will read into the headline? No.
"Alabama prisoners' organs vanish, and there's a whole lot of passing the buck" could easily be "Deceased prisoners' organs taken by University of Alabama against families wishes" but that's not going to get the clicks.
