被拘捕後是否不可以講案情

這樣不算妨礙司法公正定，既沒有向公眾透露案情，亦沒有向原告/被告或其同夥透露案情，只是朋友，須知妨礙司法公正是指具有妨礙司法公正傾向及意圖的作為、一連串作為或行為。

妨礙司法公正的例子，包括中止刑事檢控，以換取報酬；向某人提出虛假指控；向調查刑事罪行的警務人員提供虛假陳述；作出某項作為，刻 意 協 助 另 一 人 逃 避 追 捕；不 當 地 干 擾 證 人；證 人 故 意 不 出 席 聆 訊，以換取報酬；提供捏造的證據；發布文章，刻意妨礙司法公正；不當地中止檢控；使原本可能得以提出檢控的法定程序受挫。

回應雙兒, 警員不是在盤問疑犯前宣讀警誡的, 是拘捕行動時向疑犯宣告受嫌的罪行，並向該名人士宣讀拘捕警誡。警誡的內容大致是：「依家唔係事必要你講，但無論你講啲乜嘅，我都可能將佢用筆錄底，日後可能作為呈堂証供用。」

1. Case discussion is not perverting the course of justice per se.

The issue is the content of the discussion can be subject to the court's examination. For example, if a government lawyer talks to the police officer, their conversation can be questioned in an open court. Based on the same logic, a suspect's admission of the crime to a friend can be also admissible.

Based on this reason, people will refrain from discussion to avoid troubles.

2. No. By its own definition, anything that can harm the process of justice is a form of perverting the course of justice.

As defined above, case discussion is not preverting per se. But if you discuss that with certain people, like witnesses, and affect their credibility, the person committing this can be found guilty of perverting.

3. No, unless the court has issued a gag order restricting the discussion.

係辯護律師未到之前,一般被拘留人士可保持一切箴默.


當警察盤問疑犯前必須言明:
「依家問你嘅嘢,你可以有權不作回答,如你回答的有關案情,將來可能有機會作為呈堂証供.」
