I knew a guy who wanted to be a police officer in the LA area.

They gave him a psychological exam.

one of the questions was something along the lines of "you pull over a drunk driver, and it turns out to be your mother. what do you do?"

I asked him what he said.

He said he would call another officer and have him take her home.

I was thinking, wow.

He said if someone answers that they would arrest her, they wouldn't hire that person.

Took me a while to work through it and wrap my mind around all of it.

I would assume that the thinking is that someone that says they would arrest (or have arrested) their own mother, is a liar.
