Where on the metro do you normally ride? I took the Gold Line almost every day from 2016 to 2018, and there were hardly any police either on the trains or at stations. Maybe 3 times a month I would encounter some guy shouting obscenities at random riders or harassing people on the platforms. Each time, I ended up having to be the one to call the police. About 6 months after the completion of the Gold Line extension, the number of police on trains dropped off dramatically and I almost never had my ticket checked. I gave up taking the Gold Line anywhere in early 2018 because I got tired of the exposure to belligerent riders, as well as those who are foul smelling; I'm glad I can start my days without having to smell mildewy body odor.
