Thanks for that pragmatic look at the politics involved and the perceived pressure that goes both down and upwards.
At the end of the day, the BEA is just a name for a group of people charged with investigating and determining the cause(s) of an accident, making recommendations to prevent a recurrence, and publishing their findings on behalf of the French State. The people involved are professionals, and no person acting alone should have the ability to determine an outcome that is not supported by the majority.
We know full well that the justice system has the ability to turn facts around and make other determinations, but the BEA's Final Report will be the matter of aviation record.
There is one small point that will never change, and that is the time the FDR and CVR stopped recording. Neither politicians or the judicial system will ever change that.
