I'm not saying that it's harmless. What we're dealing with is a spectrum of risks here, and how we manage those risks can have a huge impact on the overall security. Even if we aren't going through Chinese companies, there still are a lot of risks that are put in place. That's effectively what I'm saying.
The other thing is that I'm more worried about the janitor than I am about the X-ray machine because, frankly, the janitor is going to have a lot more access than the X-ray machine. That's what I'm trying to say.
Look, I think the issue here is not necessarily that this is harmless or that even if it's a non-Chinese company servicing the X-ray machine there isn't an insider threat there. There is, absolutely, an insider threat, and this is why this kind of overall layered security approach that's looking at these things in steps and trying to.... Sometimes in critical infrastructure protection we talk about the Swiss cheese model, which is where you're trying to layer security so that you can't shoot through all the holes all the way through and then eventually hit some kind of vulnerability.
