Uhh... I'm not sure why you put mental problems in quotations as if it was alleged... The bitch made verbal threats, sent bomb threats, mailed a white powdery substance to people in his inner circle and was sentenced to 51 months in prison for doing so..  I'm pretty sure you can feel fairly safe saying she had some major fucking mental problems... Not sure what possible reason Kevin Spacey would have for having someone "mow down" a person that he didn't even assault because she only supposedly heard about it through a third-hand account before beginning to stalk him and his team.. she was then wholeheartedly discredited through her actions and prison sentencing and therefore would have posed literally zero threat to him........ So remind me once again why in the fuck he would give two shits about taking such a risk as to get rid of this woman who saw nothing, knew nothing, and was nothing?....  Sometimes an accident is just an accident.
