The very definition of child pornography is difficult in the legal sense. Material classified as child pornography is subjective to many variables to consider, including what defines a “child,” the modality of the material, and how the material is used (Gillespie, 2010). The article Legal Definition of Child Pornography by Alisdair Gillespie discusses how difficult it is nowadays to define parameters around a concise definition of child pornography. We live in a technologically advanced world, which makes it difficult to come up with an exact explanation of child pornography due to the ability to manipulate and create materials that may or may not depict a “real” child. Child pornography laws are a recent concept created by the obscenity law of the 1970s. However, these laws may need to be redefined to apply to today's world. Child pornography can be difficult to identify. In the 1960s, Supreme Court Justice Stewart coined the phrase “I know it when I see it,” a legal phrase that is actually still used today. Although this statement referred to obscene material in an adult pornography case, Jacobeellis v. Ohio, Judge Stewart explained that not all issues can be definitively defined, but there are some issues that do not require a specific definition to know what actions the law should take (Gillespie, 2010). The Internet poses great challenges to the law due to global involvement. Cross-border communication and distribution have made a consistent definition of child pornography impossible, which creates a weak basis in the fight against this heinous crime. Gillespie addresses identifying the factors that define what child pornography i...... middle of paper ......dare? This is the difficulty for law enforcement and, as such, some criminals could fall into the trap of justice. Gillespie presented a very interesting analysis on the definition of child pornography. The article appears strong and I believe it has raised fervent arguments about the complexity of parameterizing the definition of child pornography. He discussed three important variables in identifying child pornography and the problems associated with it. I didn't find this article to show any weaknesses, perhaps because most of the evidence presented was insightful. Gillespie's article helped me recognize the enormous difficulty law enforcement faces when it comes to defining child pornography. There is a fine line between what is legal and what is not, and the complexities of this issue will continue into the future.
