I agree with you. It's especially sad because Andrew had young children. I don't know why that should matter more, but it does - it's somehow a deeper evil.
It bothers me too because Andrew Breitbart was such a good person. I know not in their eyes, but a normal person could tell that he was very decent. I didn't know him personally, but I still feel sad and shocked about his passing. I liked him because he was of my generation. Liked 80's music. Approached things in a modern way and was full of energy. There's a big void there now.
