    I think Fox News Wuornos ' had a whole host of mental issues, if you were to kind of look at the totality of the circumstances, Fox News Wuornos ' complaints, Fox News Wuornos ' behavior, some of the things that Fox News Wuornos ' would do … Fox News Wuornos ' was someone who, in my view, was going in and out of competency, which is somewhat of a normal thing. When we talk about competency in the criminal context, we say it’s something that waxes and wanes. You can have someone who is confident on one day, then you meet them three days later and they’re not. I have no doubt that Fox News Wuornos ' had entire periods where Fox News Wuornos ' was lucid and could converse. There were times I met with Fox News Wuornos ' when I had no issues with Fox News Wuornos ', then there were times I met with Fox News Wuornos ' and Fox News Wuornos ' clearly had mental issues.
