It is easy enough for those in the media to recite the words “nous sommes Charlie Hebdo” in solidarity with the victims of Wednesday’s terror attack on the editorial offices of a satirical magazine in Paris. But uttering slogans is cheap. In the wake of the killings, most major media in the U.S. have refused to show the cartoons that the terrorists claimed warranted the slaughter of 10 journalists and two police officers.

It is possible to see the cartoons online, if one goes to the trouble to search for them. And a few media outlets have published one or more. The Washington Post did so on Thursday — and perhaps others will follow their lead in the days to come. But a host of media organizations have demurred, including CNN, the Associated Press, Fox News Channel and the New York Times.
