whether a traffic stop a fleeing suspect a tense encounter with a citizen or some sort of in progress crime body cameras are a great tool for capturing and documenting events as they unfold they also can help reassure the public by preserving evidence and putting events in perspective but make no mistake about it body cameras won't answer every question or resolve every controversy after all they don't capture everything for instance the camera might not capture a suspect twitching and tensing up as if he was getting ready to strike out or reach for a weapon or the night vision capability might be so advanced that the video might not be a true representation of what the officer was able to observe with the naked eye so let's take a look and see what they can do hands up drop that knife more in Surrey monitor would be the problem and as we all know just as with instant replays at sporting events video footage of rapidly evolving situations isn't always clear enough to prove things beyond a shadow of a doubt referees can watch plays over and over and from multiple angles and still not always make the right call however there's no doubt that using video cameras and law enforcement work has many benefits both to judges and juries the community at large and the officers themselves
