Personally, I think a teacher has a moral responsibility to teach material that he has reasonable belief is effective and sound. His reasonable belief could be established in many different ways, so I don't think it is worth arguing about what does or does not create "reasonable belief". What does it for one does not necessarily do it for another.
However, not everything works equally well for everyone, or rather, not everyone is equally capable of using the same material equally well. What is effective self defense material for one person might be useless for another. This is not necessarily the fault of the teacher. The student needs to take some responsibility to decide if they feel confident in what they are learning, and go elsewhere if that confidence is lacking. Likewise, the student needs to accept responsibility to train in a manner, under the teachers guidance, that will develop the knowledge into useable skills. But ultimately what one does with knowledge is up to them and them alone.
If a student is attacked on the street and is unable to defend himself, I don't think you can hold the instructor liable. That would be like holding your college or university liable if you are unable to find a job after earning your degree. there are far too many factors at play in the real world to be able to place blame on the university, or the martial arts instructor and claim that they failed the student.
If a teacher is teaching material that he himself has no confidence in, that is a problem. Hopefully a student can see thru the charlatan and will go elsewhere. Unfortunately, there is a certain level of caveat emptor. Nothing can be done about that.
