The United States is the first country you could draw attention to. Currently, the agri-retail facilities in the U.S. have just completed a phase of risk assessment analysis where they had to submit paperwork that was due June 7 to the Department of Homeland Security. The homeland security department will assess, then, these various retail facilities, as well as the products they're carrying, to ultimately come up with a final risk assessment that will then require regulation and stewardship of the products. There is a bill in the United States Senate currently—I believe it was the senator from Iowa, but I can't quite recall, maybe it was Ohio—where they had introduced a potential for a tax credit system to reimburse the agri-retail facilities for the costs of their upgrades. To the best of my knowledge, that's the most advanced that any country is at in terms of its security assessment.
You can well imagine that the United States is very concerned about the agricultural precursors to bomb-making. The London train bombings were agricultural bombs. The Murrah building was brought down with I think just over one tonne of ammonium nitrate. So agricultural bombs seem to be the product of choice, because they're usually acquired.... I'm not telling you anything you don't already know.
