It would have been handy to ask the original members of CID if they recollect anything about the AM. But most if not all are dead.
Don't believe Wilkes or CAL make any mention of it.
I think there is something in one of the books about JB taking an AM from SC's flat and using it at GH. But its a completely moot point. If you have time to waste with Adam going round in circles about AM's, whether or not he could see to cycle along the sea wall, whether he would drop a bollock or two hitting any pot hole etc, etc be my guest.
The only thing that can help JB 40 years post conviction is as Patrick O'Connor said in the Louis Theroux documentary:
Patrick O'Connor, Barrister, Doughty Street Chambers:
"It will have to be a slam dunk. It will have to be something of a blockbuster piece of evidence to have a chance"Note the last three words "to have a chance". Even with a slam dunk/blockbuster piece of evidence JB is fighting an uphill battle. The sort of material JB is submitting to the CCRC is nothing more than a complete joke. The CCRC must be pi**ing themselves.
