Which statement about police surveillance is true?

Surveillance activities conducted by police must be justified and comply with legislation to ensure that they respect individuals' rights and adhere to legal standards. This is crucial in maintaining accountability and protecting privacy. In New South Wales, specific laws and regulations govern how and when police can perform surveillance, including the necessity of obtaining warrants in certain situations. This legal framework is designed to balance the need for effective policing with the protection of civil liberties, ensuring that surveillance is conducted legitimately and with proper justification.

The other statements do not reflect the legal realities surrounding police surveillance. Not all activities are permissible without oversight; indeed, many require adherence to strict regulations. Police cannot simply act without such oversight, as this could infringe on individuals' rights and lead to unlawful practices. Furthermore, the requirement for documentation and reporting ensures transparency and accountability in surveillance practices, distinguishing them from arbitrary actions.
