What would putting him to death serve? Did killing McVeigh cause people to stop committing crimes?
The death penalty, as a deterrent, just isn't effective in its current state. The appeals process can drag things out for years, even decades. A person could die of natural causes before the injection/chair. In the meantime, taxpayers are footing the bill for the drawn-out appeals process and extra costs of housing a death-row inmate.
I dunno...killing Nichols will put him into the forgotten halls of our collective memory eventually but if he doesn't waive the appeals, as did McVeigh, that may take a long time.
Putting him in jail for life w/no parole he'll be forgotten sooner.
Which is better for justice?
Which is better for the families?
