I thought this was a very interesting case worth discussing. Two people, clear evidence that one of them is guilty of multiple violent crimes but evidence can't separate them. How do you prosecute them? For arguments sake lets assume the DNA testing is 100% and no evidence becomes available that separates them. Do you send them both to gaol when it is very likely that you are sending an innocent man to gaol? Or do you let them go with the very real chance that one will offend again causing much pain to other innocent people? I am quite surprised that the police here can hold and charge both suspects with the same crime.
