YOO I M SO SMART I got only 2 innocent, even though I did only asked and drawn only 2 guys.
Sketching is useless, you can find people just by looking at the most common features.
If 4 out of 5 have a small nose, the guilty guy probably has a small nose. If 4 out of 5 are white, the guy you're looking for is probably white...
In other words without sketching u can get 5% error rate
