I can quite see why answering all those questions would vital for nailing a perpetrator (named).
But I can't, for the life of me, see how any of them are remotely relevant to establishing the innocence of the McCanns.
I am not worried about establishing the innocence of the McCanns I want to know how the alleged abduction was effected.
It's a simple enough proposition. A job requiring a manning level, a time span and a slot into which that time span fits.
Detail the activity, how many men, how do they get on site, how do they get off site how long does the job take and what is the time available?
If we get to the point where the job takes 3
x minutes and there is only a 2
x time slot there is a problem.
Convoluted plans eat up time and because of the "listening train" time was few. So it had to be a quick job. On spec looks like a non starter as how would the "on spec man" know there was a child in the apartment? Burglary gone wrong gerroff pull the other one. So how was it done?
