长期以来,检察机关对监狱警察职务犯罪的查办力度不大,主要原因在于犯罪主体特殊,案件突破难。犯罪环境封闭,案件线索少。监狱警察在减刑、假释、保外就医等方面拥有较大的自由裁量权,知情者常因担心报复而选择沉默,因此导致效果不甚理想。 For a long time, the procuratorial organs have not made much efforts to investigate and handle prison crimes in prisons and policemen. The main reason lies in the fact that the criminal subjects are special and the cases are difficult to break through. Closed criminal environment, fewer clues. Prison police have greater discretion in terms of commutation of sentence, parole, and extra-medical treatment, and insiders often choose silence because of fear of retaliation, thus resulting in unsatisfactory results.
