In most of these cases, I'm sure they wouldn't actually want a video going around if it existed. They would usually rather stick with their own narrative.
That’s a very broad statement to make.... Yes some scenarios are downplayed, and when the true story comes out the subject ends up looking a lot worse. There are however many legitimate scenarios where the people in power abuse their positions big time. These guys have had long hard days to, but they are in the service industry, and they definitely can’t afford to pull stunts like that.
I personally would have loved having a video of the whole exchange, especially the end where the manager refused to give me his name, picked up my bag (is that even legal?) and threatened to call airport security.
