Please stop killing London's cyclists and pedestrians – give them good landscape architecture

Here is a video of the recent Stop Killing Cyclists protest march in Oxford Street. It was very well organised, with a theatrical dash, but did not get the media coverage it deserved. There was a massive police escort. The officers were very friendly to the marchers but I wonder if the relationship has become too cosy. The police would not have liked it but we might have achieved more if the die-in had taken place in Oxford Circus and if we had waited for the police to remove each and every demonstrator in a police van.
