I watched this, too, and found it very moving. I worked in a similar area nearby, and knew Anthony Walker well in the two years before he was murdered.
In Little Boy Blue, does anyone know the name of the boy who kept the gun in the kennel? I was thinking there was no hope for that boy - if he refused to take the gun, they'd hurt him badly, if he told the police, they'd probably kill him. I felt very sorry for him.
