I think this is a fundamental question as part of the regulatory discussion. I think deciding what is a permissible use and what is not a permissible use is very important.
We have some suggestions on this front. We think that indiscriminate mass surveillance is not something that should be permitted. We also think that discriminating against an individual on the basis of race, gender, sexual orientation or other protected characteristics should be prohibited.
Also, the democratic freedoms piece, which we discussed today, is really important, and I'm pleased to hear that it's part of the discussion. That is one to address as well in making sure that the technology is not used in a way that undermines fundamental freedoms like freedom of assembly. I think those are some core uses that we would suggest.
One that is maybe more specific to the law enforcement context as well is that we think it's important that the output of facial recognition is not used as the only reason or the only piece of evidence to take a material decision—for example, to arrest someone.
