I'm glad this came out. This admission pretty much kills any chances of successfully arguing insanity during her coming go around with the Courts again. It is a devestating admission to make, pretty much the same as saying "I'm faking" in the eyes of the Court or jury.
Inmates are subject to the same feelings the rest of us have. I would imagine that many of the inmates hate Yates. I'm not sure I would consider the testimony of another inmate as creditable.
