Years ago I discovered that video recordings are as biased as another person standing nearby and watching the scene unfold. They are, obviously, better at remembering the details than most people would be, but none the less they record information differently (at times) then what really occurred. The story that lead me to believe this is as follows:
A friend of mine and I agreed to by pepper sprayed for compensation. My friends thought this was terribly hilarious and made sure to video tape the event. Two of the people present were MP's in the airforce and had experience with Pepper Spray. On the day of the event, Isaac and I stood side by side as our other friend sprayed us both in the face. My plan to thwart the Pepper Spray was to keep my eyes closed. Isaac went to the ground immediately (as he was worried about what would happen when the pain kicked in), but I remained on my feet. After a short time, I heard on of my friends yell "Hit him again! Hit him again!" I became worried that would happen and opened my eyes to avoid being sprayed again. An orange ooze filled my vision and the pain was immediate. I hit the ground. Skipping ahead to my point… if you watch the video, you will see the events unfold in a different order. You will see me hit the ground right before he yells "Hit him again! Hit him again!"
It is important to remember when watching homemade videos the sequencing of events may be slightly off due to the delay in sound.
