Bring back the death sentence for sexual crimes against children

I write this as a concerned citizen, to those in charge as a plea to help save British society, for all people of every race and kin to come together against the true evil in our society and abolish it from this great country. Since the death penalty was abolished science has come far enough to indefinitely prove whether someone is or is not in fact guilty of these crimes and believe if someone is charged with this immoral heinous act they should be erased from our society.
