I think the Death penalty should never be abolished. First, I believe life, human life, is the most sacred consideration in our city. That said. Our system is one, like our economy, of negotiation and evaluation. Every interested party in a negotiation ends in the middle ground. But where the "middle ground" is depends upon where you start. After a serial killer is apprehended, there are families out there that want closure, what to know what happened to their loved ones. Currently a prosecutor can start out with the death penalty and end up with "life without the possibility of parole" in order to get him to disclose the location of the bodies not found. If you take that away, the only way a prosecutor can get that information is to off a chance to let a Jeffery Dahamer back out on the street one day.
In this "fight" for our nation of equality and justice, there are unintended causalities. in every case where a death penalty was applied to wrong conviction, the prosecutor was biased and hid evidence. I think the punishment if that prosecutor gets caught doing that should be one of "homicide" or "attempted homicide". Don't through out the baby with the bath water.
