While I sympathize with the McLean family's expressed grief and outrage, I do take considerable exception to this statement from Ms. deDelley:
“My concern is protecting everybody else from people like this,” said Carol deDelley, Mr. McLean's mother, who has been pushing for a new law that would prevent anyone designated NCR from being released. “For Mr. Li's safety, he needs to be in a locked treatment facility. For me, I don't care if it's in a penitentiary or a treatment facility.”
The odds of Mr. Li getting out any time soon is practically nil. This appears to be one of the rare cases where there is little dispute about his mental state, and what is necessary to treat that condition. (at least to the best of our limited abilities) Mr. Li is apt as not to be locked up in a psychiatric facility for the rest of his life - schizophrenia, especially when it results in violence, is exceptionally difficult to treat, and the odds of any treatment being declared "successful" are pretty slim. Ms. deDelley is asking for revenge, not justice.
The sad thing here is that there are two victims in this horrific crime - Mr. McLean, and Mr. Li. We should not lose sight of the tragedy that either of these people represent.
