All of the above named,would have told them apart had they been there.
Wasn't the whole point of the argument whether they could be identified as being " different " to each other,rather than who was going to see them and who wasn't ? Why has it snow-balled ??
The argument has a few different threads to it. Basically it is an attack on Julie, but only under certain conditions.
To sum it up, it is being said that if Jeremy is guilty and Julie knew this to be the case, then Julie being the one to identify the victims is a bit 'sick' or 'twisted'.
However, if Jeremy is not guilty, or Julie didn't know at the time that Jeremy was responsible, then the opinion of her identifying the victims as being 'sick', doesn't work.
Nobody (to my knowledge) has voiced an opinion that Julie identified the victims with the knowledge that they had been murdered by Jeremy. The two schools of thought are that either Jeremy is innocent, or Julie didn't believe at that stage that Jeremy had murdered them.
