On the topic of youth democracy in my last blog. Yesterday in California there was a hastily arranged demonstration for tolerance following the murder of a gay teen, Lawrence "Larry" King. The demo was arranged by two 16 year-olds, and nearly a thousand people attended - many more than expected.

Jerry Dannenberg, the school district administrator said "We forget the goodness that is in most of our kids. This tremendous turnout by kids is an expression of their voices, their opinions."

Newsround intends to deal with knife crime, but what about letting young people have a real say in what is reported. For a start that means covering the UK Youth Parliament conferences next week.
