Charlie Hebdo attack: Why U.S. cartoonists don't push boundaries

The deadly Charlie Hebdo attacks led U.S. cartoonists to ink their support for protecting First Amendment rights. But don't expect American cartoonists to push new boundaries with their work anytime soon, said Tom Richmond, president of the National Cartoonists Society.

[Charlie Hebdo] "wanted to push those buttons as hard as they could and that's what they were set out to do," he said on The Daily Circuit.

American editorial cartoonists often steer toward politically correct pieces and topics, Richmond said. Those decisions often come from consumer reaction or predicted consumer reaction.

"There are certain boundaries, culturally I think, that we in this country stay within," he said. "But things are very different in other parts of the world."
