What definition of "serious sex offenders" is used when sex offenders are so categorised.

I have asked Tony Cameron, Chief Executive of the Scottish Prison Service (SPS), to respond. His response is as follows:SPS makes the assumption that all offenders who have been sentenced to a term of imprisonment are considered serious offenders. As such, all sex offenders in custody are considered "serious". The Executive proposes to introduce, in the forthcoming Criminal Justice Bill, statutory criteria defining the highest risk offenders. In addition, the proposed Risk Management Authority will produce common standard guidelines to assist with categorising the risk such offenders pose to the public.
