I don't pretend to be an expert on it. But I can say that the advancement of technology is becoming an increasing issue for law enforcement in a very general sense, not just related to this issue, but with all the BlackBerrys, ISPs, and cellphones....
The technology is advancing so fast, and I think that as good a job as our law enforcement is doing, they're still playing catch-up. And they have a way to go to make sure they're on par with the people who use the technology for a purpose it's not intended for. I can't speak to it specifically, but in general, I think cellphones and increased technology are an issue for law enforcement.
