A teacher pulls a gun on a classroom filled with students in the latest Batman comic book -- and that's why DC Comics chose to postpone its release.

As we reported, DC Comics forbade the release of its new issue of "Batman Inc." because it "contains content that may be perceived as insensitive" in the wake of the "Dark Knight" shooting in Colorado. Now, we know exactly what that "insensitive" content is.

In addition to the teacher pointing a gun at her classroom, the issue contains several other references to gun violence -- including one moment when a character says, "Eyewitness spoke of a grisly bullet-ridden cadaver."
