The growing documentary role of video is not limited to seminal events like those described above. Video surveillance cameras are objective witnesses with perfect memories.Thus they can play a vital evidentiary role in legal proceedings -such as those involving robbery,drug trafficking,police misconduct,motor vehicle violations, and even malpractice in a hospital operating room.Indeed,whenever moving images are central to an event the video camera is superior to the written word.A written description of a hurricane,tornado,or volcanic eruption cannot convey its immediate power and awesome nature like a video record .A diary entry cannot replay that wedding reception ,dance recital,or surprise birthday party as accurately or objectively as a video record.And a real estate brochure cannot inform about the lighting, spaciousness,or general ambiance of a featured property nearly as effectively as a video.
Nonetheless,for certain other purpose written records are advantageous to and more appropriate than video records.For example , certain legal matters are best left to written documentation: video is of no practical use ha documenting the terms of a complex contratual agreement,an incorporation,or the establishment of a trust.And video is of little use when it comes to documenting a person s subjective state of mind, impressions,or reflections of an event or exprience.Indeed, to the extent that personal interpretation adds dimension and richness to the record,written documentation statistical or other quantitative information. Returning to the riot example mentioned earlier,imagine relying on a video to document the financial loss to store owners ,the number of police an firefighters involved, and so forth .Complete and accurate video documentation of such information would require video cameras at every street corner and in every aisle of every store.
