1 Journalism's first obligation is to the truth.
2 Its first loyalty is to citizens.
3Its essence is a discipline of verification.
4Its practitioners must maintain an independence from those they cover.
5 It must serve an independent monitor of power.
6 It must provide a forum for public criticism and compromise.
7 It must strive to make the significant interesting ad relevant.
8It must keep the news comprehensive ad proportional.
9 Its practitioners must be allowed to exercise their personal conscience.
