Terrorism Bill

I want to consider the point about the journalists and the mad trips. If journalists had heard a rumour that something might be going on but there was no substantial suspicion, gained entry to the relevant place, found that training was happening and then left, they would not be caught by the clause because they had left and reported the matter. It would therefore be possible for journalists to act, provided that they did not knowingly enter something that was obviously a terrorist training camp. Is that how the clause would work?
