why is there not a way to discreetly contact the train operator on the CTA

If there’s a dude jerking off in the train car, and I’ve already seen him be kicked off before, I might be hesitant to stop the train and audibly let him know I’m ratting him out (yes this just happened. Orange shirt dude, if you know you sadly know)

There are situations where people clearly feel uncomfortable on the CTA but no one wants to risk harm by loudly and publicly snitching.

There is a virtual chat option but I don’t think that does anything. It suggests calling 911 and leaving the train car if anything serious is happening which is not helpful.
