One thing it does show is that whoever wrote those notes was very very poorly.
It is amazing what handwriting experts can achieve nowadays. I couldnt make head nor tail of it but i suspect they could.
I really dont see why it bothers guilters so much that the ct do whatever they can for jb, i find it disturbing behaviour of us supposedly intelligent debators that we have to resort to slagging off the c.t. there really isnt any need for it as it will probably turn out to be of non evidential value anyway.
