DNA only proves a person was at the scene of a crime.I think back years ago when we had execution,yes there was people hanged for crimes they didn’t do,these days though we have come along way since 1969 when capital punishment was abolished,we now have DNA which obviously didn’t have back then.
Sorry this is just my opinion I don’t want to turn this thread into argument.Just have to say.
You wouldn’t rape a rapist? Steal from a thief? So why kill a killer? Revenge is NOT justice.
Im so glad the UK abolished the death penalty.
