Yes, it is, absolutely. From the first day, I personally conveyed our concern regarding fraud prevention to our chefs de mission, before they deployed.
Sometimes the involvement of the heads of mission...some of these practices, I think are almost at the level of human judgment and intuition, which even the Auditor General and his team, with respect, are probably not able to detect. They are things like the heads of mission knowing where the storage room is in the mission and what's inside, as opposed to thinking that is the responsibility of somebody else. Also, just being aware of the behaviours of locally engaged staff, so they notice when someone's lifestyle is inconsistent with their income from the mission. Then working with the management and consular officer to keep an eye on the areas of greatest risk and when there is doubt, they call home. I've been explicit with them to call home, call finance, call HR, ask for help, and not just try to figure it out on their own.
