I went to the Pasadena show on Sunday. As I approached the ticket window, I saw a young boy at the ticket window. He was talking to the ticket lady saying, "He shot himself in the knee!" I looked around but did not see anyone who appeared to be in trouble. The ticket lady pointed for the boy to go inside the convention center, then she closed the ticket window. I stood there, wondering if she would return. A few seconds later, an older man limped past the ticket window, holding his knee. He was breathing heavily. Blood was dripping from his hand where he held his knee. I watched as he limped into the convention center. The ticket lady returned and open the ticket window. I bought a ticket and entered the convention center. The injured man was sitting in a chair with his leg propped up. He was still holding his knee. Two police officers were helping him. One officer was on the phone while asking the man questions. It looked like the officer was getting vital info from injured man. I kept on moving so that I wouldn't be in the way. I don't know what eventually happened. I guess this was an accidental discharge because I assume that no one wants to shoot himself in the knee.
