Should the death penalty be re-introduced??

Should the death penalty be re-introduced??
 
What do you think?

At the moment the terms dished out for serious crime, like murder, is a joke. There is no real deterrent hence it seems potential killers, especially the young, take the decision to kill lightly.

Today’s events is a good example, 12 innocent people were killed by one man. If he was still alive now and in custody, he will only be facing a very long jail term. Is that fair??

Some here will argue that the death penalty may be wrongly issued to an innocent, but with today’s technology etc this will be very unlikely.
