Thank you for your question. I am going to answer you in English, because I am more comfortable in that language for the technical terms.
You're asking if there are existing structures that could be put in place. From a policing perspective, I think we have many partners throughout the world who are policing capital cities and who we could potentially rely upon for best practices for any existing structures.
We have changed our processes in a number of larger demonstrations based on what we've seen around the world and on some of the trends that have taken place. I think back to Nice, France, several years back. That incident altered the way we respond to major events here, in terms of making sure that we are considering all potential threats and sources of threats. I believe that's something that could be put into place.
There are places where we'll keep the area open and free at times when everything is fine, but where we can have some infrastructure that would be rapidly put in place should we face a moment of threat or crisis.
