4.13.1 Inmates complained about the methods used by the emergency support team (EST) during searches: inmates were often assaulted, their possessions destroyed or scattered about, and sometimes searches were conducted in inmates' absence. Some claimed that they were habitually given electric shocks during these searches. Many requested that the EST's procedures be explained to them, so that they knew what was required of them during such searches. The Acting Regional Commissioner explained that searches are governed by specific procedures and that ESTs are only permitted to conduct such searches with the approval of HCCs. The use of shields and teargas is only permitted in riot situations, and can only be used with the HCC's written approval.
