Freedom of the press is a sacred right in a democracy; it is a tool of democracy and should never be hindered or even examined. Many died for this freedom, so it should not be abused or used recklessly.
Charlie Hebdo had and still has the right to publish inappropriate caricatures of Muhammad, but the management owed it to freedom itself to be sensible. The magazine knew the risk, yet the highly offensive pictures were continuously distributed.
At least 12 lives were lost because Charlie Hebdo excised its right to freedom of the press. It refused to be censored, but we censor ourselves regularly: The N-word is not used in polite society because many find it offensive.
Being free means sometimes we do not do the things we are free to do, especially when it is foolish, unnecessary and dangerous.
