The worst question I ever had at an interview was "would you lie for the company/department"
What would you answer???
I think you have to base your replies on book answers for these kinds of questions. By that I mean never admit to be happy to lie, never agree that some people are less desirable than others, always be prepared to deal with safety issues head on, etc. You might feel like brown noser but come the moment for real most would not want to get into a character bashing excercise, lie for a company potentially maginifying its problems or fly with someone in charge who is sloshed.
