Is Loughner faking insanity?

[Kevin]

I was watching an interview from one of Jared Loughner's ex girlfriend's who claims that he is faking this all to gain attention and avoid the death penalty in the process. Although I'm not seeing how someone could really pull this off, it does leave me wondering how someone could actually be this insane like given all the things this guy has said both in and out of custody and the fact that in a creepy almost horror movie like move in posed in a thong with the Glock he used in the Gifford's shooting before committing the crime he did.

So does anyone think there might be any possibility to this notion put forward by his ex-girlfriend?
