From the moment Motou-kun started piecing together the look of the culprit, I felt something was wrong. I thought that he was fabricating a memory, and it turned out that he really was doing something like that.
Unfortunately this is a very real phenomenon. Eyewitness testimony is usually taken as god-tier in criminal cases, but it's actually been shown to be imperfect and severely unreliable, especially in stressful situations.
Man, the falsely-accused guy sure acts cool for someone who was just, you know, falsely-accused. I'd have been a bit pissed at the witness guy at the very least.
