On August 19, 2015, the day before the two men drove to the convention on August 20, 2015, Stumbo posted a picture of the weapons in his car online, with the caption, “Kevin Norton and I are ready for worlds Boston here we come!!!” According to Assistant District Attorney Brian Brodigan, both of them sent threatening messages to other Pokemon players, including one that said, “My AR-15 says that you lose.”
Robert Le Roy, Norton’s lawyer, said that his client and Stumbo were not aware of the differences between Massachusetts and Iowa gun laws. “They basically always drive around with loaded guns in the trunk in Iowa,” Le Roy said, calling the incident an “error in judgment.”
