1. A number of people have responded to this thread by saying, "What's the point? They just won't prosecute."

That might be true, but any decision taken improperly or for political reasons would itself be subject to scrutiny. https://twitter.com/adamhamdy/status/1264669891614912512?s=20

2. On the 27th April, I wrote a letter to my local Chief Constable. I could have chosen any one of a number of senior figures involved in the government's pandemic response, but I complained about Sir Patrick Vallance, because his statements on herd immunity were so stark.

3. I wasn't expecting much. Most likely a polite brush off. But I felt it important to make the complaint and have it recorded. The Chief Constable took the matter seriously and has assigned a detective to investigate the complaint.

4. I want to thank the Chief Constable for restoring a degree of faith in this country's institutions. Now an investigation has started, every decision taken has to be justified by law, not politics and not spin.

5. It is up to the police and CPS to decide whether there is a case to answer. For that reason, I would encourage anyone who suspects a member of the government or one of its advisors of misconduct in public office to write to their local Chief Constable.

6. If you need to, please feel free to adapt my letter as appropriate. It is important to remember we are not without rights and protection in the face of abuses of power. If you suspect a crime has been committed, report it.

7. If members of the government or its advisers have not committed misconduct they will have nothing to fear from any investigations and will be open and transparent with investigating officers.

8. If crimes have been committed, it is very important offenders are punished and removed from positions that would enable them to do further harm.
