This criminal needs to spend the morning rush in the stocks right on the subway platform, his mid-day digging subway tunnel extensions with a pick and a shovel, the evening rush back in the stocks, and his nights in a pit in the prison yard.
No, he just needs to be quickly and painlessly removed from the gene pool. Preferably by a well-armed intended victim, as the salutary lesson taught to others of his kind is far more valuable that way.
