"There are in my view no mitigating circumstances whatsoever in relation to these offences. They were separate instances, pre-meditated and planned by you. Your action showed a callous disregard for public safety and you caused contamination of good amounting to over£700,000 . Not only that, you caused considerable alarm and anxiety in the minds of those that were present. … You insisted on all the witnesses attending, despite the strength of the evidence against you, which was on any view, overwhelming. Of course, you have expressed no remorse; hardly surprising since you continue to deny [that you are] guilty. I find you to be arrogant and inflexible in your thinking. You are regarded as posing a high risk of harm to the public. You were the subject of a community order for earlier offences in 2007, and I quote directly from the pre-sentence report: “Managing his risk to the general public proved unmanageable. He has not engaged well with supervision and denies guilt in face of all the evidence. Based on his past behavior, attitude and his poor response to supervision the likelihood of re-offending is assessed as imminent. [His] risk of harm to the public is assessed as very high and he is currently managed at MATHA (sic) level 3 and is a critical public protection case.” I have taken the view that the appropriate sentence in this case is one of an indeterminate nature; in other words you would be kept in prison until it is regarded as safe to release you. My hands, however, are tied."
