The London police were initially covering up the crime to protect the suspect. Not that the media will say this so bluntly yet they do acknowledge there was a cover up to protect one of the members of the Thin Blue Gang.
The murderer/cop had been noted on at least four previous occasions exposing himself to women, assaulting women, and etc.
The spin is that the protests are against men committing violence against women, but video of the protests shows it’s against police literally getting away with murder.
The police in the UK are actually worse than in the US when it comes to misconduct because the facts on the ground are that the UK government sanctions the misconduct. Part of their broader view on how people should be ruled by the government.
