I saw a man kicked off of a flight while I was waiting at the gate for my flight. He was clearly drunk and weeping like I had never seen anyone weep. Like this man was in emotional pain. I felt so badly for him while the police had him pinned down on the ground. I wanted to say something to the police since they were being harsh to him. After sometime he calmed down and was sitting with the police at another gate down the hall. He began yelling " my son my son" and couldn't stop crying. I figured his son died while he was away and needed to get home but hit the bar to hard while waiting for his flight. Once the police and gate attendant realized something awful happened they rebooked him. I left before he did but the police stayed with him and talked with him for a few hours and seemed to comfort him.
