The last time they rushed to paint suspects as rapists ahead of any sort of actual trial, they got sued to hell for defamation when the allegations turned out to be fraudulent altogether.
I could excuse them for being a little slower on the draw this time around. "Being investigated by the FBI" does not mean the subject is automatically guilty.
My wife's ex was "being investigated by CPS" at one point. He didn't do anything, but it is/was humiliating for him nonetheless.
