As if from a Dirty Harry movie:
Mr Aldrin, famous for his participation in the Apollo 11 moon landing in 1969, hit Bart Sibrel after he approached the former astronaut outside a hotel in Beverley Hills, Los Angeles and demanded he swear on a Bible that the landing was not staged.
Mr Aldrin responded by punching Mr Sibrel, but said he merely struck out to defend himself and his stepdaughter, who was with him at the time.

Buzz Aldrin: a man pushed too far by the wild and lawless society of Beverely Hills, takes the law into his own hands and metes out his own brand of outlaw justice.
Go ahead. Ask about the apollo moon landing cover-up. Make his day.
Deputy District Attorney Elizabeth Ratinoff told Reuters news agency that a videotape shot by a cameraman hired by Mr Sibrel had shown the film-maker follow Mr Aldrin, calling him a "thief, liar and coward".
Of course, the tape could be a fabrication.
