David, how about this...
After taking over the case from a previous standpoint where Sheila Caffell was implicated - and a casefile of evidence had been assembled supporting this conclusion
In order to prosecute Jeremy Bamber, Ainsley has to:
[1] Coordinate and lead a fresh round of statement taking, including altering or burying some previous statements, that were taken prior to him taking over the case?
[2] Not have to coordinate or lead a fresh round of statement taking. Not have to alter or bury any previous statements that were taken prior to him taking over the case?
1 = conspiracy
2 = ?
