Interesting "hot takes" from folks on here. For me, it's more about a person's character. The kind of person that would intentionally evade a fare, is likely also the kind of person that could or would cause problems on the trains. A person that would likely smoke, play loud music, steal from, harass, or assault someone, or some other form of mischief.

When I see people intentionally hop the turnstile, I make sure to avoid the car they are riding on, because more than likely it will be a (censored) show for the rest of the ride.
