The way to do this in a public internet, having privelged information, is to Lead by offering food for thought to the discussion. Else your methods become the subject rather than the message.
Systemic problems and food for thought....
1) Passing the FAF below the hard altitude.
2) Descending well below minimums (busted by 1XX Feet)
3) Improper Go Around procedures
4) Possible improper use of Priority Switch
5) Switching from Managed/Managed to Selected/Selected approach just prior to commencent of the approach.
Please note, these tidbits are in no order. Nor are they all inclusive. There are other issues that will certainly be looked as contributing factors.
I have no dog in this fight. I am not trying to point fingers at anyone one group or group of pilots in this matter. I am merely trying to have people look at this accident from a very simplistic view. When the final report is issued, hopefully, you will be able to see just how simplistic and utterly avoidable this accident was.
