The argument here is that they're saying the misbehaviour is a result of the prison conditions essentially being torture, and under more humane conditions there wouldn't be the same degree of instability or loss of control. If bringing up autistic people to a normal level of behaviour was as cheap as giving them some food stamps and money for clothes, this could be more affordable than prison, as well as more humane, as well as more likely to result in said autistic person to contribute to the tax base. Autism is sometimes essentially a digestive disorder or sensory disorder which presents in the form of asocial behaviour. The difference between Autism and ASPD in this context is that changing the diet of somebody with ASPD won't make them any less sociopathic, but changing the diet of somebody with autism will.
