Under criminal procedure regulation, what must not be disclosed on written statements?

The correct answer focuses on protecting the privacy and confidentiality of sensitive personal information. Under criminal procedure regulations, certain details such as addresses, dates of birth, and phone numbers should not be disclosed in written statements to safeguard individuals' identities and personal data. This ensures that witnesses or victims are not put at risk of harassment or intimidation, particularly in sensitive cases.

The reasoning behind restricting this information is rooted in broader privacy laws and the need for the criminal justice system to balance transparency with the rights of individuals involved in a case. By keeping such personal information private, the legal process helps to maintain the integrity of testimonies while also protecting the rights of individuals.
