Morality aside - very few journo's have any anyway - can you imagine the legal minefield the authorities would have to go through in attempting to prosecute someone for doing this?
It's a sad fact that most tabloid papers will print all sorts of crap about any story, so long as they think it will sell newspapers. They know that those affected by what they print seldom have the resources to take them on in court, and even when they do, the cost of any damages awarded is miniscule compared to the income derived from publishing the original story.
As those of you who work at the UK's bigger airports may be aware, it's no secret that some 'spotters' work in teams from the viewing areas, videoing movements and recording atc in the hope of catching an incident, which thy then sell on to the media.
