Here in the USA, if the Connecticut POS wouldn't have committed suicide, this is what would happen. After a trial that might happen 1 to 2 years after the crime was committed and take a month, the POS would probably get life in prison and endless appeals.
If the POS was sentenced to death, the POS would get endless appeals and probably die of old age or at the hands of another inmate.
There’s another difference. In China, they have gun control, so the head cases use knives instead.
