This is how we keep officers honest. Every officer knows the importance of making careful detailed notes of every aspect of their investigation as they will need to refer to it, sometimes months or years later, to refresh their memory. The content of an officer’s notes forms the basis of their cross-examination at trial. If it’s not in their notes we assume, in court it’s because it didn’t happen. Poor note taking loses cases.
