Queensland's 'Jack's Law' proposal allows police to use metal detectors at public venues to curb knife violence.

Western Australia Police Union is pushing for 'Jack's Law' to be adopted in WA, including at shopping centres.

WA Premier Roger Cook confirms the government is considering the law and drafting legislation.

The law could permit police to use metal detection wands at sporting events, pubs, clubs, and late-night stores.

Since its 2021 trial inception, 'Jack's Law' has led to numerous scans and weapon confiscations.

The legislation includes additional measures such as hiring new police officers and increasing court transparency.

Concerns arise over potential racial profiling, civil liberties infringement, and extended police search powers.

Victim groups demand stronger support and tougher penalties, while opposition critiques juvenile offender management and sentencing practices.
