I have watched animal planet, discovery channel, History channel and national geographic and science channels a lot for years. Why don't they show actual footage of the real animals, like big foot, loch ness monster, big exotic cats in american forests and suspected dinosaurs living in Africa? I believe they have actual footage but don't want to release it to the media? They just show the evidence of what could be there but seems like they just try to keep up the suspense for the audience.
