Thank you very much for your question. It's something, again, that we consider thoughtfully and often.
There are two parts to the answer. The first one is our transparency report, which I would urge you to take a look at. It's published twice a year at transparency.twitter.com. In it we report, by government, what kinds of requests we have for takedowns, be they for information purpose or emergency takedowns. We report on how often we have completed them.
I think—and I could be wrong—in the previous report we complied with 100% of requests from the Canadian government, and it was a small number, like 38.
You can go and check that resource to see how we interact with governments. Of course, we're also governed by international rules and agreements. MLAT would be the law enforcement one that would govern how we work with other governments through Homeland Security in the U.S.
Finally, with regard to law enforcement, we work with them consistently. I was at RCMP headquarters yesterday to have discussions about whether they are getting the information they need from us, whether our reporting is helpful and sufficient in cases like child sexual exploitation and if they have enough of what they need to prosecute, and also that they understand what our limitations are and how we go through and assess reports.
