I think we had heard testimony that this would be, on a cost basis, a practical basis, and an evidentiary basis, a bit of a disaster.
To me, there's a big difference in police stations...and that's what we're talking about. They'd have to physically have the equipment in place at these stations to record this. You'd have to have a technician to conduct the recording. In my view, there's a big difference between an interrogation that's recorded--you can see what's going on, you can see the dialogue, you can hear the conversation--and something like this that's recorded, a scientific test.
The bottom line is that we heard evidence that this would be extremely problematic. I can just see, perhaps during a trial, where it's going to be a video itself that comes into play. We'll have testimony on the video itself--the video is too grainy, someone walked in front of the camera at a certain critical moment, and so on. We heard in testimony that these tests are in a very controlled environment--they're scientific, done by extremely experienced people--and that there would be a huge cost to implementing this.
For those reasons and probably more, the government doesn't support putting this burden on local police departments throughout the country.
