Green Police

In New Jersey, USA, a team of cops and scientists is 'busting' polluters. For the first time a film crew has been given total access to their operations. 40 Minutes follows the trail - the surveillance. the 'sting', the raid. Whether it's one small operator dumping chemicals on the street or the president of a multi-million-dollar company caught polluting a river - both are likely to face serious criminal charges. In New Jersey, they believe only tough action will deter dumpers. Is there a lesson for us in Britain?
