It's long overdue, a rewriting of the mental health act to allow the authorities to take addicts and  those with Mental Health problems into forced medical custody and treatment.
The majority of crimes are committed by individuals from this community and it's hard to argue that they don't need compulsory treatment. Unfortunately any such  actions invariably run against our constitution's right to liberty and thus no one can touch them.
 If an amendment to the constitution is the only answer then let's look at an amendment because it's obvious to me that there is no provision in the law to look after people who can't look after themselves. 
What happens right now is that people with addiction and mental  health problems are criminalised, locked up and then tossed out on the street again with no committed treatment
