The next prosecution, that of Thomas Walker, of Manchester, and six others broke down in a way highly discreditable to the authorities. Walker's services to the cause of Reform had, as we have seen, been conspicuous alike in energy and moderation, and his enemies in the Church and King Club made great exertions in order to procure a conviction. The archives of the Home Office throw a sinister light on their methods. A magistrate of Manchester, the Rev. John Griffith, informed the Home Secretary that Booth, a man who was imprisoned in June 1793 for seditious practices, made a declaration against Thomas Walker and McCullum, members of the local Constitutional Society. According to Booth, McCullum had said: "Petitioning Parliament be d----d. You may as well petition the devil to reform himself. The only way is for each Society to send a number of delegates to a certain place, and there declare themselves the Representatives of the People and support themselves as such." Thomas Walker had also said that each member must have a musket, for they would soon want them.[315] But it transpired in the trial of Walker, McCullum, and others that Griffith had let Booth see that he wanted to incriminate Walker. He not only offered Booth his pardon for such evidence, but left him alone with Dunn, a malicious perjurer, the falsity of whose charges against Walker was convincingly demonstrated.[316] The case proves how far an unscrupulous magistrate could succeed in getting charges trumped up against an innocent man who opposed him in politics. Doubtless in other cases personal spite, or the desire of a reward, led to the offer of false charges; and the student who peruses the Home Office archives needs to remember the Greek caution, +memnesth' apistein+, as much as if he were perusing French Memoirs.
