 that attention to the threat. Over the years, we've seen some of the rules for federal buildings or some of the requirements for federal buildings change. You see these big planters, obviously, in front or these things to stop cars from driving in. You see the setback, for instance, new office buildings. Is that all part of the understanding the threats and how to mitigate risks? Has that been part of what OBEB has been doing, working with other agencies and is part of this interagency partnership?
