For sure obeying to ethical rules is very important in any profession. However when it comes to journalism, it is especially quite a tough job to obey these rules. You have to be careful with your relations, however you have to have some relations to be able to get some news too. Moreover, as you dont know what you may have to report in the future, it is almost impossible for you to be careful with all your relationships. It seems that you have to have very distant relationships with your environment to be able to be a true journalist.
Do you know any journalist who covered an important issue about one of their relatives? Do you know any journalists who continued to write at his column even after he strictly criticize his editor in his column? Personally I don’t know, but if you know such journalists please share with us.
