I am new on here, hello. I was looking at the general discussions and I saw yours, which made me very curious. So I looked it up and I heard the Ukraine on Youtube that occured on August 11, 2011. The person that is video tapeing shoots down at pedestrians on the sidewalk. I thought that it was strange how these pedestrians were just walking casually. Now if I would have been there walking outside, I would have been looking all around the area for that sound. I just thought it was kind of strange how it didn't affect them. Although, it was weird sounding.
