The movie's frequently stated message is to ferret out the reasons for endemic American gun violence so as to prevent violence in the future.
There is archival and very disturbing footage from the school shootings at Columbine High School; the footage is blurry and hard to make out but may nonetheless disturb young or sensitive viewers. There is also war footage from Kosovo, several sequences featuring cartoon violence, still photos and video of assassinations, murders and a suicide (though gore is light). These sequences are short, but still quite disturbing.
A couple of sequences feature guns being fired by scantily dressed women, or show armed women in revealing outfits. A Marilyn Manson album featuring a man with (fake) breasts and a vagina is shown briefly.
Some cursing and derogatory language, including "fag," "f--k" and "s--t."
Many brands are mentioned, such as Lockheed Martin and Kmart; the actions of said companies are often criticized.
Drinking, Drugs & Smoking
A few brief references to drinking and one interview subject smokes during the interview.
