6.4 Security 6.4.1 This programme has consistently received the largest share of the DCS' total budget, but has reaped little benefit: escapes, deaths and assault remain all too prevalent. It is noted that the DCS intends to reduce assaults to less than 4 162 escapes to less than 60 and unnatural deaths to less than 50. Furthermore the DCS intends to increase the number of centres with access control security turnstiles to 78 and that 7 percent of officials will be vetted in 2011/12. Concerns about assaults and deaths in detention and escapes from correctional centres have consistently been raised, particularly given in many cases officials are involved.
