I welcome they took it to an US court. There a doubts on the procedures followed during training, if they even followed them, and now they have to look at in detail, explain judge and jury as an independent.
I suspect they also had doubts whether this would lead to an appropriate discussion on improvements, if taken to an European court. A biased jurisdiction does no good for intelligence transparency.
So, I strongly belief this US lawsuit is aimed to make things better and not an ambulance chaser raid, not only for the fact that the German AOPA president is one of the lawyers filing.
