If you think that either has stores to last more than a few days for a large population like an average city, then you're delusional. That seizure will do nothing to protect them, the citizens of the city, or anything else. The moment that any LEO or governor has to seize stockpiles of anything is the moment that there is nothing left to protect. Only a fool would stick around. Delaying the inevitable for an extra few days is meaningless. Far more likely is that the stores will be used for bribes and escaping.
Never thought of myself as delusional but I guess I would be the last to realize my condition, hehehehe.
I am from the Upper Midwest and many millions of bushels of grain are stored at shipping points along the Mississippi and other waterways as well as at terminals in Duluth/Superior. Just as in the event of a nuclear exchange, food supplies to the citizenry is not going to take the form of croissants and frozen entrees. It will take the form of wheat, corn and soybeans and you better know how to deal with it (slaking the corn, soaking and milling the grain) if you want to survive.
I won't squabble about it.
