Back to the point. The death penalty is a deterant. If someone thinks that he will be killed for his crime he will either do a better job or not do it. The Americval system is as bad as the English system. Although I don't like to say it, the French have a better system.
All evidence is presented as it is gathered.
Enough of my waffle, I am in favour, as long as the trial system is up to the responsability. It seems Canada and Western Europe are ahead of us in the area of the death penalty, it is abolished there. They have realized it is simple-minded, barbaric, and vengeful, nothing more. It does not deter crime, furthermore, when questioned victims' families overwhelmingly report that after the convicted killer's murder they feel no greater sense of closure. You cannot have it both ways. as far as the expense, again, to have proper justice you must have appeals, attempts to prove your innocence before the ultimate sentence is handed down.
