They behaved that way because they're Brits. Brits cannot go abroad without making complete pricks of themselves. The Hatton fans at the Hatton/Pacquiao weigh-in had their share of thugs who hurled racial abuse at Pac & Khan, as well as randomly abusing Shane Mosley. It's not a racial or religious thing, it's a national thing. 70% of Brits should be banned from having a passport that allows them to leave the country.

Also Khan shouldn't get the blame for his fans any more than Hatton, Pacquiao or Mayweather should for how their fans behave. It was clear the people who were actually with Khan were not encouraging it.
