I think you are right. The logistics of maneuver and communication during difficult times are hard enough for those that are prepared. Without intel, maps, transportation, comms, etc... looters won't have much chance.

Individual looters will be a problem, and perhaps groups small enough to fit in a single vehicle. Massive hordes of looters are unlikely IMO.
Doesn’t mean the sheriffs dept or national guard couldn’t be going door to door. We know the military has already held exercises simulating such events.
