25% died (overdose on drugs), and 21% returned to the streets. We need to recognize that drug addicts don't make rational decisions for themselves. We shouldn't leave them on the streets to do drugs, we shouldn't give them free housing to do drugs, we should put them in rehab. If they don't want to go to rehab, charge them with possession of illegal substances and put them in a prison rehab system. This type of life crippling drug addiction shouldn't be tolerated.
I recognize that not all homeless are drug addicts, they should be supported in a much different way than we support drug addicts.
