Presumed failure as a crime scene witness.

I would make the very worst crime scene witness. See, I have a really awful memory for people - routinely forgetting who the hell you are at any given opportunity - it's like I don't fully absorb strangers' faces. This is an annoying trait to have at my job as people will come in multiple times and it's obvious that I helped them before by their demeanor and conversation. As they trill "Durr, I bet you're sick of seeing my face!", I have to fake acknowledgement because really no, I'm not sick of seeing their face, because my brain is telling me in no uncertain terms that I have never seen their face before in my whole life.

It's not exclusively work related of course - I've been introduced to lots of my boyfriend's friends who I really wouldn't be able to pick out of a crowd. Usually, since I'm never quite sure if I've met the person before, if Ben didn't make a point of introducing me during the particular confusion-inducing interaction, then I assume that we have met and afterward ask him "Who was that person and why am I supposed to know who they are?"

When Mary and I lived together in Etobicztan, I was introduced to several of the girls in her Theatre Production program. Even though these young women looked exactly-nothing alike, I could not for the life of me keep any of them straight. She would mention one of her school friends, and I'd ask "Is that the blond one?", exasperated and baffled Mary would have to explain that no, it wasn't the blond one, it was a girl I had met at least 6 times previously. News to me.

So I really would be a terrible crime scene witness. If asked to describe someone I've only seen once and in the lightening fast instance of say, a robbery taking place, I suspect all I'd be able to tell the police would be "Um... it was a dude. About... dude height."
