I’m just surprised the train didn’t have a pull cable or panic button or similar to force the train to stop...
I wondered about the emergency button, too. The videos show emergency buttons next to the exits.
I just found this 2023 story about a fight with a knife on the same transit line in the same neighborhood: https://www.wcnc.com/article/news/crime/charlotte-light-rail-train-stabbing-video-blue-line/275-66652ef8-3502-4138-ad50-705fe5886f1a
That time, a passenger hit the emergency stop button, the train stopped, and everyone exited - including the people who were fighting.
But that situation was different. This time, a crazy maniac flipped out and attacked an innocent young woman, and then he walked around, talking to himself. Maybe hitting the emergency button would’ve set him off again.
We’re all thinking about what we’d do in that situation. But, have you ever been totally oblivious to something terrible that happened right in front of you? Once, for example, a young man drowned in the ocean, and none of us at the beach - not even his group of friends and family - noticed. I’ll always feel sick about that.
