I fit the description: I was between 5'3" and 5'11" and my skin color can be described as "coffee with a touch of milk."
Video evidence that showed, fifteen minutes before it happened, that I was 13km away at a wedding having dinner wasn't enough since I could have left immediately after the footage was taken and driven down.
I still have video evidence of the senior detective basically instructing the witness to select me out of a lineup. They also whispered to each other throughout which I only managed to hear thanks to some expensive headphones I had.
I made fake Facebook accounts and befriended all of the "witnesses" and victims. Beat the case on a technicality thanks to a post I found on Facebook by a eye witness.
I'd still be in jail right now 9.5 years later.
I'd say it happens extremely frequently, it's just that the people it happens to aren't as lucky as I am.
It's not something I'm particularly proud of or something I talk about - outside of my immediate family no one really knows all of the details, and only a handful of people outside of my immediate family know about it. It's the most traumatic experience of my life and had significant consequences on my mental health that still affect me daily.
My blind optimism helped me through it, but it had really hurt my family too.
Good luck and I'm glad the optimism paid off!
The general rule is not to talk to the police at all. Ask for an attorney if you're being detained; leave if not.
The line-up I mentioned was a photo line-up, where they place one of my mugshots among a group of other photoshopped mugshots.
They arrested me in the first instance, then released me, then arrested me again and charged me after they had performed the photo line-up.
