I imagine it was simple as "This guy in a Scarecrow mask was seen around other ghouls, so MUST BE A GHOUL". They made an assumption, and gave a C-rating due to having no evidence of aggression or attacks.

It seems like Amon hinted at it, but then Kaneki talked about being scared so he ended up not saying anything.
