A moot point when the deaf rely on them! and some terps rather enjoying the limelight too much. The overwhelming issue is the too high profile of Interpreters and the tendency then for others to relate to them, not YOU! Their very presence acts as a barrier by default, and interpreters really need to step away from acting as 'go-between' to the extent the client is being sidelined. Some of their outrageous antics in musical access needs addressing too, as it isn't about them.
The empathy with interpreters needs addressing, we need greater 'distance', more formality, and less familiarity with them, as this breeds contempt and misunderstanding, as well as deaf assuming terps, will help them make decisions or advise them, (which they are not allowed to do). There is evidence some terps are doing that to 'help' which can mean adverse legal decisions being taken against the deaf person in some situations.
With the Interpreters refusing to validate what help they give a deaf person even in a court of law, deaf people need to be more aware of what their support entails and to make further access provision to validate what transpires within the system. You accept or demand an Interpreter, you accept whatever result (good or bad), that results afterwards with no way to appeal. No interpreter will testify on your behalf, on the grounds the court adjudge it hearsay and the terps have to rely on memory. Some legal areas won't even allow you to use a terp you are familiar with.
What is lacking is a real code of ethical behaviour and back up for the client. As it stands only the Interpreter is backed to say nothing, and there is no real body monitoring interpreters approaches. Or who have the ability to remove an Interpreter who violates the client's confidence or privacy. It's time interpreters came in out of the cold and became answerable when mistakes are made, also that textual back up is made available to all deaf and HoH clients as proof of proceedings, given the legal aspect of non-recognition of interpreters presence at the job face, deaf have no witnesses to events.
To a major extent, terps are already invisible to the system regardless of how very visible they are to deaf people and the close relationship they have with them. Deaf need to get wise for their own sake.
