Depending on how often you find yourself in bizarre, hilarious or thrilling situations, many events in life deserve to be caught on video. But the unexpected moments tend to pass right by, undocumented, simply because it's usually pretty cumbersome to whip out a video cam and get it going in time. Unless you've already got a camera in your hand with your thumb on the Rec button, that ridiculous person / automotive near miss / crook -- or cop -- behaving badly will never be digitally immortalized.
