They should have trained security on staff which should have been capable of bringing that drunk guy down. A bouncer could have easily taken him down in less than a minute. Hell back when I was in my prime I probably could have taken him down myself. The staff appears incompetent.
Have you seen the staff on RC. These guys are short, tiny and thin, many from Philippines or other 3rd world countries. The drunk guy is tall and weighs how much? We really don’t know the whole story yet, but I can see where they would do their best to detain him and had to medicate. They were in international waters too, so laws are different. Not trying to be argumentative just another perspective.
