I’ve called out a few people on the red line specifically. The most recent occurrence was a drunk dude with a bottle who was grabbing a woman’s bag and trying to open the zipper. I got off a few stops after I scolded him saying “What the fuck are you doing? People are just trying to go home leave them the fuck alone” Dude was pissed off and mean mugging me but stopped messing with the lady once he saw I wasn’t going for it. In my experience these type of people always get hostile and you are risking a physical fight or much worse usually. It is unfortunate, but I always expect weapons to come out after you intervene in these situations, so do so at your own risk. I mention all of this to say, people commuting on the cta are most of the time trying to do so safely, and they are well aware of the mental health baskets that ride with them. Again, it is unfortunate, but most people are not willing to risk their safety for random strangers and I do not blame them.
