It does sound like the police simply couldn't be arsed.
What did police do before the existence of CCTV cameras?
@334bu I hadn't thought of a homophobic attack, but yes, that is probably what it started out as.
I just thought bog-standard rape. It reminded of one time in my youth when I was attacked by a group of men and nearly raped, though fortunately no knives were involved.
In other words, the mentaliy of these men is that if transmen think they are going to be safer now that they have a beard, they are going to teach them that they are still exposed to the dangers of being a woman.
