I wholeheartedly agree with you Roch. JB had fully relied upon the law to do their job-----and they let him down badly ! Unforgiveable !!
How would he know in advance that a medical professional would not take temperatures at the scene? How could he know in advance, that a medical professional would not establish times of death for victims, that did not fit with timeline set by his own claims?
How can he ensure that a struggle with Nevill or Sheila (a mother with fingernails, potentially fighting for her children's lives) or that furniture being bumped in to, would not cause him to have visible marks on his own person?
If he can't guarantee that he will not be marked during the killing of five people, in a confined space with furniture, what is his plan B to explain the marks?
He turns up to meet the police with a black eye or scratches and claims 'oh yeah.. that's just a coincidence.. nothing to do with anything that happened here'.
It's laughable Lookout.
