There's your problem. It's the journalist's choice whether some random bloke looking for his brother is a 'source' or not. If my brother ever goes missing after a terrorist attack I would just be a confused, angry and upset individual with no particular insights into terrorism or any other current affairs.
And journalists aren't stupid, so anyone approaching me in such a scenario would only be interested in bottling my tears and selling them on for a profit, I would not serve the purpose as a valuable 'source' by any definition of the term.
