I lived across the road. It sounds amusing when you read it as a news story but it was a pretty awful situation. The police basically had a grudge match against a bunch of noisy, but basically harmless kids. I saw a police dog being set on a woman who was bitten several times - she wasn't even in the house, she was one of a group of local squatters who turned up to witness and help if they could. Another policeman dragged a woman up the street to a van - by her hair, she was screaming and crying in pain.
No, not very nice.
My upstairs neighbour was with me and when we shouted and remonstrated with police because of their appalling behaviour (we were loud but polite) we were threatened with arrest. I had a kid indoors so couldn't do more - I wanted to get my camera but was afraid that I might be arrested if I started taking photographs.
The behaviour of the police was so bad that weeks later when I got a letter from a solicitor representing the people in the house, I gave a full statement and later appeared in court as a witness for the defence. The police side of the story was worthy of the Booker Prize, let's say.
I'm delighted to say that all were acquitted.
There's a lot more to the story (there always is!), but that's the bare bones. I didn't really know the squatters, just to say hello to, and I asked them to be a bit quieter sometimes - which they always did.
