The five murdered women were working as prostitutes. If newspaper reports are accurate, they were all heroin/crack cocaine users. By working to fund their habits they are at risk daily. Also, addicts who repeatedly shoplift and end up in prison must cost more to keep in prison than to treat with controlled doses of drugs in the community.
I think these people are beyond the 'Just Say No' campaigns reach. As addicts, they will always put themselves (and others, in many cases) at risk to get the funds to buy drugs.
Any thoughts?
