@oralloy,
."......In reality, Guede's crimes would not have continued if he had not been released "....
but he was released, and he did continue.....and?
Here's a few more contentious "what ifs".......what if Kercher had not acted like a totally insensitive sociopathic weirdo immediately after the event, and had showed genuine concern, respect and shock/horror like the vast majority of rightminded humans would have, in similar circumstances?
What if the Italian Police were actually capable of organising a piss-up in a brewery, and carried out all the forensic procedures properly?
What if the poor victim had realised sooner that she was sharing accommodation with a weirdo sociopath, and had found somewhere else to live?
We could speculate forever...
