This is not an isolated incident. The police have a history of lying
The police log in this case looks similar to other untruthful police logs. The mentioning of the members of the public looking shocked and the large amount of swear words against police. Police officers are doing these things because there are no consequence of doing them, their superiors are either party to this kinds of conduct or just turn a blind eye. It is institutional and it will take generations to clean it up.
We can not have the rule of law if our Police are institutionalized in professional lying.
The length the faked details of the off duty police officer went in to, in the email sent to the MP, suggests these are well practiced police tactics.
