You're right, I suppose I was just inferring his intent. But from the facts that have been released, it looks like he just posted screenshots of his successful "hack" on 4chan, and didn't try to do anything more nefarious like steal her identity. I could be wrong.
I think my reaction would have been the same had it been Obama, Biden, or any public figure. One big difference for me anyway, would have been if he had accessed a @whitehouse.gov address (whether Bush, Obama or other official). Being able to figure out her pet's name or whatever seems somewhat trivial to merit a jail sentence.
