Big Hairy Ian writes "An American expert in violent self-defense has been excluded from entering the UK by the Home Office. From the article: 'Tim Larkin tried to board a plane from his home in Las Vegas on Tuesday, but was given a UK Border Agency letter saying "his presence here was not conducive to the public good." Mr Larkin, who was due to host seminars, told the BBC the move was a "gross over-reaction." The Home Office said he was subject to an exclusion order. A spokeswoman said: "The home secretary will seek to exclude an individual if she considers that his or her presence in the UK is not conducive to the public good." Mr Larkin — who trained as a US Navy Seal — runs a company teaching combat to military and law enforcement clients in the United States.'"
