Positive:
1) Freedom of press eloquently demonstrates a concept of free speech which is one of the most important aspects of democracy.
2) The truth in independnent newspapers usually prevails over lies, which is definately a good thing.
3) An objectivity is very important since it gives people an opportunity to analyze adequatly what relly is going on and say if there is something wrong. Helps to refine a situation.
Nagative:
1) Some newspapers may abuse their freedom and write some unfair defamation, which lack objectivity and adequate evaluation.
2) This may lead to anarchy if there is too much freedom.
3) Transperancy of information has not only positive sides as one may think. There are many cases when it's better to hide some information, so that the vast majority of people can live safely.
Controvercial:
The situation with Wikileaks.
