Not that this will help, but we had a baggage issue with jetBlue a few years ago and we were impressed with how they handled it, although we were very frustrated at the time.

We got off of a late JFK-SJU flight at around 12:30 AM. At baggage claim, my dad's suitcase came down the baggage claim completely open with his clothing hanging out. Naturally he was very upset by this. It got even worse when we attempted to close the suitcase and the frame was so badly bent that it was not possible to close. We spoke to the baggage service supervisor at SJU who was not exactly the most people friendly and continued to tell us that we were not entitled to anything and jetBlue had no liability. With enough persistence, we got him to call jetBlue Central Baggage Services, who after explaining the whole story informed the local supervisor that we were entitled to full compensation for a new bag. We went out the next day, bought a suitcase from Marshall's in San Juan, and on our return trip back through the airport, they cut my dad a check for the amount he paid with a receipt.

So we were very frustrated at 1 AM with the baggage service office, but eventually got a fair outcome after speaking with the right people. I completely understand your frustration and have been in your situation before with other airlines, but as a frequent traveller with AA, DL/NW, and B6, trust me the baggage issues are no different from carrier to carrier. Also, I am fairly certain that whatever "security camera" to see if the bag got loaded that you keep referring to will NOT be consulted in the search for your bag. Things just don't work like that.
