Li has a human right to be allowed walks outside for fresh air and sunshine. His actions towards McLean were unintentional and out of Li`s control. He should not be further punished or deprived for an act which he had no control over. To deny him this basic human right would be inhumane and uncivilized. This man is in a completely different and improved mental state than when he murdered McLean. He is essentially, a different person and a much less dangerous person. Allowing him to go outside, will not present a risk to anybody. He will be closely supervised at all times. I do not see the problem. The mentally ill need to be treated with respect and dignity at all times, to help improve their mental condition. Depriving somebody of sunshine and from going outside, can lead to the worsening of your mental state as depression is more likely.
Politicians are using individual cases such as this one, to score points. The doctors and review board members are trained, educated and knowledgeable, and they know what they are doing. If they felt Li presented a risk to the public, they would not allow these walks. They are making the right decision by allowing hi to go outside.
There would be no reason, other than revenge and vengeance, to deny Li the right to go outside. Vengeance is not justice. Justice means treating people who are mentally ill with fairness equanimity.
