We do think that facial recognition can have applications in the security and law enforcement context. I think what's really important to note here is that we take a risk-based approach to how we assess using a system and the kinds of customers that we will work with.
We have our sensitive use review process that I mentioned, with those three triggers. Anytime we're going to deploy a system—whether it's facial recognition or something else—in a way that will hit one of those three triggers, we go through a robust sensitive use review process.
We do make our facial recognition available for law enforcement and security uses. We think technology can have some useful applications in those scenarios, but it's really important that there be robust safeguards around that use, including the internal safeguards I've mentioned at Microsoft, but also a regulatory framework that ensures that we're all clear on how the technology is being used and know that it's being used in a way that is trustworthy and responsible.
