theory: someone who pulls a gun and shoots someone else over a small argument can be reasonably judged to be mentally impaired in some fashion, based solely on the facts of the case. discuss?
note that mentally impaired/deranged/completely psychotic does not have anything to do with being legally insane, which means only that at the time of the crime you were not in a condition to be able to judge the rightness of what you were doing and/or be aware of consequences. and some other legal mumbojumbo, but that's pretty much it. you can have a chorus of 50 elves and flying fish tell you to shoot someone, but if you know it's wrong to shoot people, you're legally right as rain.
