To me I don't believe attacking the sea wall route would do much justice. Even by highlighting its impracticalties.
EP tested all the routes. Bamber had access to a bike, he could walk, and he owned a car. Wilkinson drove the route so it must have been suspected at one point by officer(s) in the 2nd investigation that driving was a viable option.
500 people were interviewed in the locality and not one person saw Jeremy Bamber, which to me is why the sea wall was settled on. Although it termed in court " as a route that avoids the back roads"
It was a small sleepy hamlet, Not Sheffield parkway on a Friday afternoon.
