You need to stop being so opinionated. Leave it to the old people. There are a few modern pieces of equipment on that plane that recorded data which could be useful in the investigation.
The aircraft has a CVR that will probably be downloaded to figure out what was the cockpit environment that led to this error. Human factors is a big thing, and punishing the pilots is not always the right (or only) action to be taken. Maybe an aircraft fault or ATC comm distracted them. Or something else. Understanding how the crew got there is very important, and their recollection of the event might not match reality that well.
The airplane records a lot of data that might be overwritten if it's allowed to continue flying. You need to secure it all before that can happen.
