Swat team attack

Before the opening ceremony started the swat team attack came repelling down the stadium. They  came out shooting down the stadium roof. We had a huge shock. I seen a swat come out with a Uzi shooting the terrorist. I saw a terrorist shooting down the stadium. It was a loud frightening noise . The noise was like a giant banging on the door. It was frightening for the kids that came to support their countries. One Terrorist came and nearly killed a athlete with a Uzi. But the swat came and defeated that terrorist. The swat team had body armor and hard helmets so the terrorist couldn't shoot them. Then after all we heard a man call out on the speaker that it was just a test. But the whole stadium came down.
