What else are you supposed to do with an unruly, drunk and psychotic passenger? He is a danger to other passengers and crew. Plus I doubt it was a room steward that injected him. They have a full medical crew on-board. Would love to see his bloodwork. No doubt their actions contributed to his death, but so did he. He may have had a bad heart, he was obese too. I hope RC fights this, personal responsibility has gone out the window.
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.
