There are a number of positive changes compared to the original text, but some shortcomings still exist. For instance, although the legislation recognizes the right against compulsory self-incrimination, it does not acknowledge the right to silence and retains the obligation of the accused to confess; the amended provisions are more tolerant of the use of illegal tactics like ＂threats,＂ ＂enticement＂ and ＂deceit＂ to obtain confessions; the legislative approach does not resolutely deter unlawful search and seizure in the collection of evidence; and although there are provisions for protection of persona/safety, financial compensation and judicial sanctions to ensure that witnesses appear before court to testify, there are no provisions on the most important rule in the evidence system, the hearsay rule.展开更多
