Questioning witnesses is literally the DA's job. That doesn't magically stop being the case just because the witness is an expert. The DA is indeed qualified for this. You could even say it's one of the main reasons the DA exists.
The author of this post admitted that it took him countless hours to discover that medicine basically has this issue wrong and only after being particularly motivated to do so. If the DA has so much medical expertise that they know better than the doctors, then what exactly is he doing being a DA?
The idea that the main purpose of the DA is to know better than doctors is ludicrous.
So to be plain: No, DA's don't (and aren't supposed to) just take experts by their word. They ask clarifying questions, and often bring additional experts offering contradicting testimony.
Do you seriously think courts operate by "the doctor said so, case closed"? We wouldn't need courts if that were the case.

For certain things.. yes. If a doctor tells a jury that these injuries could only be sustained via shaking trauma, most juries will believe them over a rogue doctor or a non doctor. Doctors have some of the highest trust ratings of all professions. Attorneys have some of the lowest. That means convincing the jury the doctors are wrong.
The blame should lay at the feet of the medical professional bodies.
