I think it would be a nightmare. We have videos that we use for training, and the problem we have with those is that we're talking about a two-dimensional view. For example, with the walk and turn, if the camera is behind the subject, you can't see if the person actually touches their heel to toe. If you put the camera so you can see the heel to toe, you can't see if they are looking at their feet, what their arms are doing. You have to have a cameraman following the subject, and multiple angles, in order to capture everything that we're gathering during the evaluation. At roadside, I've worked with the in-car cameras in the past, and they don't pick up very much because of the angle they're placed at. In a police station, there are so many things you're not going to see. You'd actually miss more than you'd capture. Then you run into the keeping of the videos, where the video is edited, because of course they'll be digital now with the technology. Many police departments simply could not afford to go with that technology.
In theory, it's a nice idea, but overall, the reality is very impractical and I don't think we'd gain anything. In fact, I believe we would have far more questions from trying to watch a video than we would have answered by seeing that same video.
