Sounds like on a world with 7 billion people for each crime there are on average 7 people that can be convicted using the incontrovertible evidence delivered by the DNA lab.
- asdff 4y agoDo all 7 people have a motive and no alibi? Probably not.
- tinus_hn 4y agoWho knows, chances are most of them are related.
- asdff 4y agoI think you know what a rare lightning strike of an even this would be and how without DNA evidence, conclusions would be even more dubious.
- tinus_hn 4y agoSorry, if the chances are one in a billion, and there’s 7 billion to choose from it’s actually not rare at all. That’s why you should be very careful to either use this kind of evidence either to find a suspect or as proof, and not both. But I’m sure we all know there’s plenty of ‘tough on crime’ judges that wouldn’t care about convicting someone based on this kind of seemingly rare occurrence.
- asdff 4y agoEvery piece of evidence presented in the court room has some probability of implicating someone else. That's why multiple pieces are generally presented.
