You know, it's hard to imagine that you would -- how you feel. You have to be in a person's shoes really to understand. Obviously, me being extremely close to him, I could tell that he was uncomfortable. But our family could never know that he would -- how uncomfortable he really was.

"He taught me everything I know about TV production and he just really wanted to serve," he said. (My father) wanted to make a statement.
