What action should police take when assessing intoxicated individuals in public places?

The most appropriate action when assessing intoxicated individuals in public places is to seize liquor from minors. In New South Wales, it is illegal for minors (those under the age of 18) to possess or consume alcohol in public spaces. By seizing liquor from minors, the police are effectively enforcing the law aimed at protecting young people from the dangers associated with alcohol consumption, including health risks and potential for irresponsible behavior.

This proactive measure helps to deter underage drinking and contributes to safer public environments. It aligns with law enforcement's responsibility to uphold legal standards while also addressing community concerns regarding youth and alcohol.

The other options do not adequately address the specific legal obligations and public safety concerns that arise when dealing with intoxicated individuals, especially minors. Issuing warnings only may not have the necessary deterrent effect, providing medical assistance is essential but typically focuses on individuals in medical distress rather than addressing possession of alcohol, and filing reports without intervention does not engage with the immediate issues of public safety and compliance with the law regarding minors.
