Defending capital punishment

Why not extend the concept to its logical conclusion? If an innocent person is executed, let's execute the prosecutor, the judge, every member of the jury, every witness against them, and everyproson employee who participated in the execution. Or do we just finally admit that we are imperfect beings who can make a mistake and acknowledge that we should allow mistakes to be corrected?

I find it odd that the united states 'the last refuge of christianity in the western world' still endorses capital punishment. Does the bible not say ''thou shalt not kill'' and preach forgiveness? How can they reconcile this kind of hypocrisy?
