Hyper local news

Jay Rosen, amongst others, has been promoting the idea of hyper local news for some time -using the web to find out things that are never going to make it into current news and only hit the local papers after the event. Tonight when I arrived at Amersham station there were about 30 police, dogs and what appeared to be a metal detector being used to scan kids, I guess for knives. It seemed way over the top for a routine operation but a quick Google search for "amersham station police today" lead to this link which explained that it was!
