I bet the FA didn't like the push-back from the customer, told the pilot the family was out of control, thus causing the diversion. Just for an FA power trip. Reading the FT boards, it has happened before and will happen again.
I think this is the bigger issue than the actual content onscreen. I've read of other on board incidents where it appears that a member of the flight crew exaggerated or fabricated a "threat."
The flight crew knows that they can call someone a "threat" and there's no consequence if that accusation is frivolous or patently false. I agree that people who are in fact a "threat" should face the law, but shouldn't flight crew who falsely accuse a passenger of being a threat also face legal consequence? I know that on the ground, if I make a false statement to law enforcement, I can be charged with a crime.
There is a lack of objective oversight of the flight crew. First, how is the flight crew qualified to assess what is a threat to the flight? Is there a standard criteria that has to be met to determine a threat? What are those criteria? Does anyone in the crew have special training in threat assessment? Second, is there an impartial third party on board who can verify the accuracy of either the flight crew or the passenger? Or is there a professional and qualified third party on board who can actually assess threats?
Perhaps it's time to install video or audio recorders on flights so passengers have recourse from false accusations, and so flight crew have verification when a passenger is an actual threat, and law enforcement has evidence with which to prosecute.
I've been fortunate so far to have good experiences with flight crews when travelling, but I have to say that I'm really concerned about the lack of recourse for a passenger if he or she is tagged as a "threat."
Even in this thread, some posters seem to have assumed that the parents must have somehow done something wrong. We don't know that. The little bit of reading I've done on the links provided doesn't suggest they necessarily did anything wrong.
The rest of the story here is just window dressing. Personally, I think the person at United who is in charge of IFE dropped the ball. As the director of "Alex Cross" stated, people on board an aircraft do not have the choice to "opt out" of watching IFE.
The airline should consider the entire aircraft a business space. That is what it is. Just like I can't control people behaving inappropriately in a store that I patronize, I can't control what someone else watches on their personal device. However, I would speak up to a store manager if they had policies I disagreed with (if I cared enough, that is. If not, I would cease doing business there). I do know that if a place of business (whether on the ground or in the sky) has content that I find objectionable, I'll mention it (if I care), and how I'm treated by the business will then determine whether I continue to do business there. The main difference in the sky is that I don't have the capability to remove myself from the situation to which I object.
Since Continental merged with United, I've heard lots of feedback from people who flew on United about the horrible service. This is just one more (unverified) example of that. This doesn't put United in a favorable light and I'm likely to consider that when choosing a carrier. But I'm fortunate to have some choices, being in a metropolitan area. Folks in other areas may only have one carrier that serves their larger community. So I don't think it's always productive to tell people to shop around. They may not be able to (just like I don't have a choice in cable TV provider).
