I'll do my best.
When I was growing up, my father refused to buy a colour TV until they perfected it. It's not about the technology. Who cares about the technology? Moore's law tells us that the technology is going to change in two years anyway. It's about what we're trying to do with the technology. What is the application? What are the processes that we want to employ?
Why would I ever—no offence—want to start a biometric file on anyone? I'm not sure what good that does. Again, I'm not an expert, but I do know that each of our governments has some sort of certification and documentation of who we're supposed to be, and we're just moving forward so that somehow, in today's state-of-the-art technology, it's real easy for me to put my photograph on somebody else's passport. So now I want to take advantage of the state-of-the-art technology that exists. So to sit there and say, “That is my fingerprint, my iris, my retinal scan”....
When you get into law enforcement, then we have uses for DNA samples. But now that gets very touchy, because that's intrusive. That requires giving a sample. It gets complicated. But that's law enforcement.
You need to know what you want to do with the technology. That's the critical factor, I believe.
