When the gangster colin gunn was brought down, it turned out that a cop had been paid to join the police. He'd ben in the police for seven years and was being paid up to two thousand pounds a month on top of his police wages - plus bonuses for good information. The problem is that one of the standing directives from the home office to chief constables is to maintain public confidence. If the public knew the extent of corruption, then i think the public would quite quickly demand change of their mps.
