I oppose the death penalty for Aurora shooter James Holmes (and all murderers) -- it's too damn good! But so are prisons' libraries and weight rooms. Make him repay society via:
1.) Work: sort garbage for recycling, dig ditches for America's infrastructure, pick crops for America's farmers;
2.) Tests: new drugs, treatments, surgical techniques, food additives (eliminate animal tests, PETA!);
3.) Donations: blood weekly, spinal fluid and marrow monthly, half his liver annually (it grows back), one kidney/lung/eye, etc.
