Bit of a guess here, but probably if you know the person we’ll enough to identify their mouth or hair, you probably already know the story and would figure out by that anyways?

I think if you don’t expect it to be anyone you know, the eyes, nose and ears which are usually covered by that bar cover enough to make it difficult.

Like think if you could spot your own mom in a line up of women her age.

Now think if you could spot a kid that you met once at a party, that you don’t even know is in the line up.
