Nonsense! This group were arrested very quickly, as they travelled away from Birmingham, probably because they fitted the profile for the likely suspects.
If the Police had an informant who could identify the group involved, why were they not arrested before the event? Or do you believe that the Police allowed the bombing to happen to protect the existence of an informant?
Sorry, but I think you are talking absolute tosh. But anyway, as I said, this is in danger of diverting us from the main argument.
