Practicality of being a bold journalist

Journalism is part of society. Journalism may reveal hidden massacres, hidden stories and histories. Journalism is not just a profession. It is an art of reengineering a society. It is an art of articulating the truths in an ambitious, pervasive and courageous way. But there is a doubt about being a bold journalist when examining the practicality of it. Is it true journalists always say truth? At present era, journalism is used to advertise a political party or some powerful individual. Journalists are fear to be frank because they want to save their lives. They are blackmailed in gun points. They are not allowed to go everywhere. News is censored and free journalism is no more in the world. Of course Europe countries somewhat encourage free journalism but it is desecrated in eastern countries. Anyway a pen is more powerful than a gun because a gun is ever used to destroy something and hide the massacres in the gun point. But a pen is ever used to encourage good things and reveal the truths to the society. Good journalist is a power of mass, representative of development of a society and truths. Journalism is not used to salute any powerful guy in a society and advertise any politician.
