/mɪsˈprɪʒən ʌv ˈtriːzən/ – Phrase
Definition: việc không tố giác tội phản quốc, việc che giấu tội phản quốc.
A more thorough explanation: Misprision of treason is a legal term that refers to the act of concealing or neglecting to report treason or a treasonable plot that a person knows about. It is a crime in itself and involves the deliberate concealment of treasonous activities rather than active participation in them.
Example: The defendant was charged with misprision of treason for failing to report his knowledge of a plot to overthrow the government.
