Freedom of information is a part of the freedom of speech, which is a human rights principle this entitles people to be able to say anything they want and not get in trouble. Freedom of information has one difference, it has to be the truth or else its slandering. The most commonly known profession to use freedom of information is a reporter, for TV or a news paper.


Censorship is the complete opposite of freedom of information, censorship is used to block any delecot information like military positions in letters going home just in case the enemy get a hold of it.
