David Irving(I've read his book, and he's far from a neo-nazi), Robert Faurisson, and Ernst Zundel. As far as I'm aware of, few people whom have been arrested are sympathetic towards Hitler or his actions.
Oh really?
re David Irving: The English court found that Irving was an active Holocaust denier, antisemite, and racist, who "associates with right-wing extremists who promote neo-Nazism",[5]
