On Wednesday's Backchat we're talking about proposals to tighten up monitoring of psychiatric patients with violent tendencie, in the wake of the horrific double-murder at a Diamond Hill mall earlier this month.

For now, patients who were admitted to hospital involuntarily and are diagnosed to have violent tendencies must comply with certain conditions even after they're discharged, such as requirements on taking their medication and attending follow-up consultations.

But these conditions cannot currently be imposed on patients who were admitted on a voluntary basis — who make up the majority of psychiatric patients.

Lawmakers say it's time to change this, and the government should consider imposing legal requirements on voluntarily-admitted patients as well.

Will such requirements help psychiatric patients? Can it make the city safer?

After 9:45am, we'll look at the Polytechnic University's study on a pneumonia superbug treatment.
