The poster is referring to the joint enterprise killer of Kenneth Rothwell whom the CAB in London decided in their wisdom to employ and this after he was previously employed by another branch in the Midlands.
The poster used the plural. Are you suggesting she was exaggerating and there is only one known example?
Also, is it automatically wrong to employ murderers? Are they never to be employed once leaving prison?
I am not sure what the point is.
I can see that in certain roles, those who have previously committed crimes and are deemed no longer to be a threat could be an asset for their understanding of the prison system for example. I would expect that the CAB has a certain number of clients who are either awaiting trial, sentence or are ex-offenders as well as family members of such people who might benefit from genuine first-hand knowledge of the system.
I would not condone the employment of certain classes of offender in all roles in society but would never deny the possibility of employment to every ex-offender.
To return to the topic of this thread though, it should be remembered that the McCanns are as yet entirely innocent of any crime and as I have pointed out they may be welcomed by the Missing People Charity simply because they are the best known parents of a missing child and can therefore bring the most publicity and money to the cause. And as with someone who was a convicted murderer has shown, Leslie Grantham, it is possible for the public to see beyond the surface.
