The original review is what I found interesting. OP seems to distract a little of the seriousness of the review but does contain interesting follow up links.
How can an account of driving a car to kill someone possibly pass ethics? It's a crime or it's made up.
Let alone how did she really for sure know who the murderer was? The review sounds like is was through gossip.
This book is supposed to be scientific, although good science can be done without ethics, generally it's a flag it's not. Which we also see from the research in the original review that she just made stuff up.
And what if she though the killer was working in a gas factory and the bullet hit a tank and the whole place exploded?
Maybe we should not get upset for BS hypotheticals.
And I seriously want you to imagine your friend being murdered, and then tell me you'd act completely rational about it. I certainly wouldn't. Or that you wouldn't want to hunt down the killer, let alone just ride in the car.
In any case, I'm not arguing that it's not illegal, and she should have omitted it. I'm just saying I find it very hard to get upset, let alone want to disband the entire field of ethnography.
