My second argument for keeping capital punishment is that it can provide a safer environment for us. How many times has something like this appeared in a national television show or newspapers about a recently captured killer walks free from death because he planned the whole murder plot purposely in a state where capital punishment do not exist? I bet many of us have either heard of it or seen it before. Many killers plan their plots ahead of time, because they know even if they get caught by the policeman they are not going to be faced with a capital punishment. It is simply due to the fact that many states in the America have not yet legalized capital punishment.
