I'm so sorry this happened to you. This is why I'm glad they will be installing new fare gates. POSs like this shouldn't be allowed on the train, and I can almost guarantee you he didn't pay. Everyone deserves a safe, comfortable ride.

I'd also make sure you have reported this to Metro and even post on Metro GM Randy Clarke's Twitter. He is very active on there, and unlike previous GMs, he seems to genuinely care about the people who ride Metro.
