DOC lacks funding

Here is a post on The Real Costs of Prison blog relating a Wichita Eagle article reporting on the underfunding of drug treatment for Kansas parolees. My experience leads me to believe that this is simply a symptom of a wider lack of funding to help persons back into society. All sorts of pre- and post-parole programs have been cut in the last 10-15 years. I think most people at DOC (and in community corrections) want to help clients (and prevent future crimes), but are hamstrung by a lack of resources. Many legislators are glad to warehouse people, but is it really "tough on crime" to just make criminals more likely to reoffend than when they went into prison? Shouldn't we want our legislators to actually fund things that will reduce future crime?
