I remember when I took Quentin Tarantino with me to a very private screening of the documentary 'Roman Polanski: Wanted and Desired ' which shows some of the legal irregularities of his case. I was involved by the film and it was an amazing experience to see people weep at the end of it.
I would often find myself at the age of 21 at midnight running down a dark street on my own with 10 men chasing me. And the fact they had cameras in their hands made that legal.
I think a child should be allowed to take his father's or mother's name at will on coming of age. Paternity is a legal fiction.
