The use of pseudo-legal language such as "intentionally and knowingly" makes this all sounds like someone looking to bring a lawsuit.
If you think you have a lawsuit, then go sue. Let us know how it goes.
If you want to be reasonable, forget about this and move on with your life (along with the passport and its visas which would thankfully returned).
By the way, it is far from obvious why you won't name the air carrier or why it was that anyone needed to take your passport anywhere.
