Gay hate singer Bounty Killer is seen in this video boasting of wanting to murder gay and lesbian people.

Leading human rights activist Peter Tatchell has said that the Metropolitan police would cancel a concert in London by a reggae artist notorious for his homophobic lyrics if there was a riot, but they ignore “polite, peaceful lobbying.”

Mr Tatchell said that Bounty Killer has been granted a visa by the Home Office to perform in the UK, despite the fact that inciting murder is a serious criminal offence.

The veretan campaigner said that he would not be organising a protest at the concert in Stratford on Sunday as it would be too dangerous.

“The Metropolitan police would only cancel the concert if there is a likelihood of public disorder – in other words they will only halt the concert if we riot.

“They are fully intent on ignoring polite peaceful lobbying – the Met will only respond to threats of violence.”

Mr Tatchell, who is a parliamentary candidate for the Green party, is furious that Bounty Killer has been given permission to perform by the Home Office.

“Police officers are beng sacked for being members of the BNP, yet this guy incites murder and they do nothing.

“There is a clear correlation between murder music and homophobic violence, especially in Jamaica, where the release of anti-gay tracks often coincides with a rise in queer-bashing violence,” said Mr Tatchell.

A second video, too distressing to be shown here, records the attempted lynching of a gay man in Jamaica. You can hear the attackers shout the lyrics from murder music songs: “Batty men fi dead (queers must die).”

Mr Tatchell has called on people to complain to the Jamaican High Commissioner to London.
