It’s a good presentation and a worthwhile message. However explaining it takes away some of the impact because your underlying information is weak.
In your first quotation, the writer asserts, “School shootings have become a common occurrence in recent years, which can be supported by the fact that as of 2019, according to The Atlantic, gun violence “has killed nearly 1,200 children in the United States since the school massacre in Parkland, Florida” (Wong, 2019).”
As of May 5, 2020, the number of students killed in K-12 public schools with firearms since January 1, 2018 is 50. This includes accidents, suicides, gang violence, escalations of fights, and a middle-aged night school student murdered by her husband. 27 students have been killed in “school shootings” and 22 of those were at Marjory Stoneman Douglas High School and at Santa Fe High School. Two more were killed at Marshall County High School in January 2018.
In 2019, a total of three students were murdered in two indiscriminate shootings, one in Colorado, another in California. The shooter in the California incident was one of five gun-related suicides. The remainder of the 12 gun-related student deaths reported in 2019 involved gang violence, escalation of fights, and one incident in which a student standing outside the school was caught in the crossfire between two gangs.
So your source is attempting to create hysteria by implying there is a link between school shootings and the deaths of 1,200 children when no such link exists. In terms of probability, a school-aged child is safer in an American K-12 public school than they are anywhere else, including their own home.
I am glad that you admit that your goal was to create propaganda. No doubt this is needed to combat all the messages urging students to bring guns to school.
You really didn’t need to provide any rationale for your artwork. Kids should not bring guns to school. It’s illegal; it’s dangerous; there is no need for it. It’s also true that students (or any other young person) should not have a gun without parental knowledge and approval. That’s also illegal and dangerous.
But you also should not use inaccurate or misleading sources. You shouldn’t use them because you don’t need them. Teen suicide is a legitimate problem; gang violence is a legitimate problem; you don’t need to invoke the specter of something that is far less of a problem than mass shootings, which apparently are manifestations of other problems. This includes the Parkland shooting, which had far less to do with guns than it had with the inability of adults, including education and law enforcement professionals, to deal with a seriously troubled youth and the incompetence of those same adults when it came to avoiding what has been called the most preventable school shooting in history.
