It's pretty clear to us that the problems are fueled by alcohol. We understand that it's a good thing people are using mass transit when they are under the influence, but then there is that attendant problem - their judgment gets impaired.

It's fairly common to have some kind of incident. It's rare that there isn't a disruptive situation. It may just be someone who is drunk and screaming.

Drivers are instructed and trained that if someone becomes disruptive, we call law enforcement. On a number of occasions, when the police have been called, it has resulted in arrest.
