He certainly could be lying, thats true. This issue forms the basis of the "Dispatches" programme on tonight, I think.
@AoG you said this
"Like I said "it doesn't say much for the credibility", he could be lying, as has already been pointed out, so why is it important that we now know about the alleged actions of the police spies?"
I am not sure I understand the point you are trying to make - it must surely be extremely important to democracy, to public confidence in the police, and for the police force to retain its authority and its ability to police with consent that allegations of underhand or illegal tactics by the police are investigated as soon as they become public?
And historical allegations are equally important, especially when linked to such a high profile case as the Lawrence case.
I mean - are you trying to argue that it is unimportant or unnecessary that we know when the police carry out such tactics?
