So now we have quotas for suspicious activity that air Marshalls are expected to meet. No reports, no raise.
As a result the genuine information being gathered is being polluted by bogus entries put in by people who were making sure of their raise. In the end the good data will end up being thrown out because it is not possible to sort the good from the bad.
Graham Greene wrote about this type of activity in 'Our Man in Havana'. It is a good read by a former intelligence officer.
