In what scenarios can police officers use "preventive detention"?

Preventive detention is a specific power reserved for situations that involve serious threats to public safety, particularly in relation to terrorism. Under the Terrorism (Police Powers) Act 2002 in New South Wales, police officers are enabled to detain individuals who are suspected of being involved in terrorism-related offenses. This legal framework allows law enforcement to act proactively to prevent potential terrorist acts by restricting the freedom of individuals who might pose a significant threat.

This measure is distinct from other general policing powers, as it is designed explicitly for high-stakes scenarios involving national security. The rationale behind this legislative provision is to provide law enforcement agencies with the necessary tools to act swiftly in preventing acts of terrorism, thereby protecting the public and maintaining safety. Other scenarios listed, such as general crime investigations or public disturbances, do not fall under the same urgent and serious threat classification that warrants preventive detention.
