I agree with the posters who said you just don't threaten (or, warn of the upcoming) violence mid flight and expect no action to be taken.
I didn't really pick up on any body language in that video but I was expecting the other passengers to be up in arms from her description and they seem rather passive.
I don't mean to be offensive but is it usual for a 15 year old diagnosed at 3 to so little in the way of coping methods? I agree that the daughter does look fine, but the way the mother describes it seems to indicate she has none?
^Then two police officers approached our row. They said they needed us to exit the plane. I said, "Why?" The officer asked if Juliette was scratching someone. I again said, "no." I told them asked for hot food to prevent a melt down and said we wanted to prevent her getting to the point of being upset or scratching which she sometimes does in frustration. I told the officer the flight attendant gave her hot food and she has been fine the whole trip. The officer said they we were going to still have us exit the plane. I told him this makes no sense. Nothing had happened. Passengers around us were telling the officers that Juliette was fine and there was no problem. The officer told us "The captain is not comfortable flying to Portland with your daughter on the plane. You have to leave the plane." The captain had never seen Juliette nor had he come out of the front cabin.
All the time they were talking to me, Juliette was happily watching her video. The officer asked us again to quietly exit the plane. I was furious. I stood and shouted so the passengers could hear. "Is there anyone on this plane who feels threatened by our Juliette who faces autism? Has Juliette alarmed or harmed anyone on this plane? Passengers stood up for Juliette and shouted, "She is fine," "Leave her alone." "She is not causing a problem lets go to Portland." "This is ridiculous," and mouthed to me "I am so sorry."
The police repeated that we needed to leave the plane. The captain came out and we saw him for the first time. He said, "Let's not make this situation worse. I said, "You made it worse. You never even saw Juliette and I have no idea what your flight attendant told you but nothing happened." I was so shaken and tears begin to fall. As mom I could not stand the way Juliette was being treated. I said I am not leaving the plane until I have statements and names showing there was NO issue. The officer said he would take statements. He came off the plane with 10 pages of passenger statements and showed them to me. He said, "You know we have some really violent cases where the plane should land. This is not one of those. You have a lot of people supporting your claim that nothing happened and your daughter should stay on the plane." He gave me the police report number and told me I can get copies of the report and the statements.^
What she describes and what happens on the video don't match. ;)
