As I thankfully have never been exposed to the community work system, I don't know how it is determined and allocated
Nor do I, although probation officers have told me the privatised Community Rehabilitation Companies (
CRC) who now administer the scheme can be quite creative.
If a defendant has a particular skill it might be put to use, which in Rooney's case would be something to do with football.
Many defendants are feckless young men in their 20s with no skills or qualifications, so they would get the old standbys of litter picking, graffiti removal, or tidying public open spaces.
There are a couple of places I pass on rides where I occasionally see the local CRC van parked and a squad defendants nearby.
