Jared Loughner who recently killed nine people and attempted to kill a member of Congress, is pleading not guilty in his trial. It's a known fact that he murdered people, including a child, and now is hoping to not get sentenced to time in jail or potentially the death penalty, but may get sent to a mental institution. The question about whether Loughner should be senetenced to a jail sentence or not should not even be an issue. They can use as a defense that he was mentally ill, but there is no evidence that he was mentally ill prior to the shootings, and it still allows him to potentially harm other people, which is why he should be sentenced to life in jail, or even the death penalty. I believe that he was completely aware of what he was doing, and there is no justification for his actions.
