So you don't really know then. Neither do I.
IMO unless one can see some clear personal advantage to a a person's decision to take one certain path instead of another one - then one has to assume there is nothing sinister about it.
As the McCanns apparently already had the power to control the media, government officials , agencies etc. then surely they didn't need to employ any outside help.
As you have seen all the videos, could you say what Richard Hall's conspiracy theory was - re the employment of PI's and Kennedy's involvement please?
Actually, I haven't seen all 4 videos.
The fourth one is of interest.
As to media control, look up the actions of Carter-Ruck in this case, and the threat of libel action, which to put it mildly has put off the press running stories, but you know that.
When did you last see an interview with the mccanns when they were asked questions beyond the parameters of the Mitchell PR mchine ?
We have seen such 'events' in Portugal, where the press do ask questions avoided in the UK and the subsequent raising of the hackles of the mccanns.
Have you ever asked yourself why many people don't believe the mccanns story ?
Similarly, do you really believe all members of the UK Police force believe their story either ?
