Answer:
I was in the movie theater when all of that happened. I went with my friend to the premiere, we were both very excited as it was the first time we were on a premiere. The evening was really blissful, there were big film stars and Mr. President himself sitting in the cabin of the theater.
After about 10 minutes of the movie suddenly a guy on third row started shouting something. After that he stood up went right in the front of the screen, and shot the secretary of president, he afterwards shouted, next time it will be your head dear President.
