According to earlier media reports, the prosecution arising from this incident was due to be heard in the Crown Court today. While I was looking for news, I came across this older report in the Independent, which includes a complete version of the CPS's statement about its decisionaking.http://www.independent.co.uk/news/uk/cr ... 64746.html
In terms of what prompted this thread - cyclists being required to use the pedestrians' gate - this bit of the CPS's statement deals with it:
Downing Street is a high-risk target that is guarded at all times by armed police officers and protected by two pairs of main security gates. A legal order made in 2008 because of the fear of terrorist attack means that no-one may use the street unless they are authorised or directed by a police officer. Officers were instructed only to open the main gates for motor vehicles and there was a publicised policy to that effect.
I presume that "publicised" implies more publicity than "published."
With regard to what I presume is the imminent trial, I'll quote this from the same CPS statement:
PC Keith Wallis now stands accused of a criminal offence and is entitled to a fair trial. Care should be taken that nothing is reported which may prejudice his trial.
