Why was only one man, Judge Greer, the determinant of the facts in Terri's case?
In most other cases, it is a jury that determines the facts. Certainly the facts in all capital cases are determined by a jury.
Qualified individuals can make wise judgments. An individual can also make horrific judgments. Our society has determined that groups of individuals are more likely to be wise. That is why we have city councils, company boards of directors, and jury trials. Groups of people tend to be "less imperfect" than single individuals.
Setting aside personalities, as distasteful as they appear to be, having only one person determine the facts seems to be the central failing of the judicial system in Terri's case. For the future, that failing could be solved by legislative action.
...I'm not going to condone or condemn this judge, but, I heard something this morning, that Greer made his original decision based on a Florida state law giving the spouse control over a situation such as this. Don't know, anyone heard this???
