Newshound points to a post from CBS News London producer Peter Bluff – “Barack, Belfast, And “Torn Down” Walls”. The linked video appears to be from 2005/6, but is interesting viewing nonetheless, and the background to the video is online here.
Here’s the sign-off from Peter Bluff
The Northern Ireland Office is simplistic. It will tell you that local communities, fearful of continuing violence, have themselves demanded many of the walls be built. Everywhere in Northern Ireland people know about Obama’s speech one man said ruefully: “Remember, in Berlin, it was the people who broke down the wall. In Belfast, it’s the people who demand it gets built higher.”
