The Crown Office told The Herald Scotland

“This system…gives police the discretion to issue a warning for offences which they consider to be very minor in nature. They will not be used for any offence of violence. This system provides a mechanism that is timely and proportionate, avoids the need for the preparation and submission of a standard police report, and enables the Procurator Fiscal and court to focus on more serious crimes while giving police the range of powers they need to respond quickly and appropriately to very minor offences.”
