First of all it is an insult and an outrage to the millions of the truly insane who never kill anyone.
Then there are the "life imprisonment" idiots.
There is nothing from keeping these human bricks from volunteering to support a killer for the rest of his/her life. Just don't make me or any other taxpayer do it against our will.
Anyone convicted of killing two or more persons should die. Quickly and without exception. Insane or not.
Good idea, let's make them responsible for supporting those on death row. Set a price per head for each murderer, say $40,000 per year, and keep as many alive as the contributions will fund.
