The whole idea of "incompetent to stand trial" is fucking nonsense. If you're too "incompetent" to understand that you shouldn't butcher an innocent woman on the train, you should die. Period. Arrest, convict, execute. You are not fit to be a part of human society. How many more innocent people must we sacrifice for the sake of coddling and babying the absolute scum of the Earth? Our ancestors had it right. They would have had this guy hanging from the gallows an hour after conviction. The old system of justice was light years better than this insane bullshit we're dealing with now.
