I was going to comment on this in another place, under another alias, but decided that the possible reasons for why this charge has been brought now and whether the outcome has already been decided, were just too 'French' for me.
The French Authorities and Legal System are sometimes in opposition but often appear to be 'in bed' together, especially when it is felt a scapegoat is required, or at least appearances must be maintained.
Whoops my cynicism is showing!.
