Irritating. I’m certainly no legal expert but it does occur to me that the victims the guy shot deserve to have their say in court - all of them. If twenty people testifying constitutes an unfair level of persuasion then maybe - I’m going out on a limb here - maybe he shouldn’t have shot them?
To me a crazy person is more like someone who bolts out of their door with a sock on their hand barking like a dog and ends up floating face down in the river.
This “Joker” knew what he was doing along with the consequences. He should have been executed long ago.
