Missouri takes the creation, promotion and possession of child pornography very seriously. The term "child porn" is used when the person depicted in the pornographic materials is younger than 18. Child pornography criminal penalties can be serious. However, when the child is or even appears to be 14 or younger, the potential penalties can be even greater.
Under Missouri law, filming or photographing a person under 18 in a sexual manner, or forcing them to perform in such a manner is illegal. So is showing or selling them materials that are sexually-explicit. It should also be noted that "Promoting child porn of a minor under or appearing to be under 18" is considered "promoting child pornography in the second degree."
