What would your answer be to Professor Ryan's question?

In 3x8, professor Ryan asks the question that most should remember if they've seen it.

The question is: "A woman witnessed a stabbing in a nightclub. She's pretty sure the assailant is black, and she's positive he has a scar on his right arm.

There's 400 people in the nightclub, so it would take forever to question everyone. Of course, the longer it takes, the higher the chance they forget important parts of the stabbing that took place. If you don't catch them tonight, then you probably won't ever catch him at all.

What do you do? Question all the black men, question all the men regardless, or question everyone?"

So what would your answer be to the question? Curious to see what everyone's thought is on it now that I'm rewatching this show for the 14th time, lol
