What's the point of highlighting discrepancies and interrogating?

Doesn't that just waste time? Why not just reject them right away?

You can do that at the beginning of the game. Later on, you'll be asked to highlight the discrepance before denying someone... ;)

Also, should you like to detain people, highlighting and interrogating can lead to that option.
