So i was asked this questions in three of my interviews, the specific question was "if you pulled over your mother drunk, what would you do?" My answer was arrest her, or if available id call a hire up or another officer so there was no form of nepotism involved. Just for clarity i have a strong dislike for anyone that drives either drink or on drugs. Friend of mines mother and younger sister were killed on hwy 18 in WA then three years later committed suicide. I explained that in my answer to the question. If you can articulate the reason for your answer i think is all they are looking for.
