Dispatches gains exclusive access to go undercover with the British Transport Police's crime unit to expose racism, homophobia and anti-Semitism by football fans on Britain's trains. Reporter Morland Sanders investigates as ordinary passengers are subjected to shocking abuse. One youth sings anti-Semitic songs, and another group of fans subject travellers to their racism - all caught on secret cameras. The cops try to track them down and put them away. Paul Crowther, the BTP's most senior police officer, discloses that anti-social and abusive behaviour on Britain's trains by football supporters is under-reported by the public because it is tolerated as part of 'football culture'.
