The theory that a free press is required for a free society. Some laws/statues don't apply to journalists, or there are exemptions for journalists, and some laws explicitly protect journalists. For the most part though, what protects journalists are the same laws that protect non-journalists. As journalists are involved in the judicial process, the finding of the courts are applied in a way that they would apply to anyone in that situation, not just journalists. Another way to interpret this: the actions of a concerned citizen documenting people breaking the law. Example: If you saw a woman being chased by a man waving a knife in the air, and you started filming it, and they both ran into a building marked "PRIVATE - NO TRESPASSERS", should the person documenting this event simply wait outside? Or follow them in, at the very least to document what appears to be an attack, and potentially help? Would this person be charged with trespass? (IANAL, but you can see how regardless of a 'journalistic standard' these situations could become less than simple)
