"But I then apply the imposition guidelines. You do have some strong mitigation and you have shown that you would comply with rehabilitation and Probation can work with you. Immediate custody would not cause significant harm to others. But, in my judgment, you are a risk to the public. You have not fully opened up with Probation or the authorities as to your level of gang and firearm involvement. I have found that you were a highly trusted member of a gang, cleaning and minding a working firearm on behalf of [others]. In my judgment, weighing up all the relevant factors, including the will of Parliament and deterrence in cases of this nature, the overriding balance is that appropriate punishment can only be achieved by immediate custody."
