Causes and effects aside, and mitigation, the NTSB has been releasing a lot more info a lot faster than I am used to seeing after a fatal accident.
Regarding information release, ALPA's justifiable complaint with the NTSB in this case, and the relationship between FOQA and flight safety,
I recommend a look at posts by PJ2 in the thread discussing another very controversial wreck (AF 447) which has elements of systemic overreilance on automation as a factor.
The post I linked to is an explanation to a question by a novice. It may be worth going a few posts up to see the conversation start and then digest PJ2's explanation in the linked post.
For all the complaints I have seen in this thread about the FAA, US airports, and ATC in large cities, I'd ask our foreign colleagues to consider how important to safety culture the FAA's approach has been to flight data from accidents, legal protections, and more. (The US military has a similar accident data protection system in place)
