I have a theory for that. Maybe Cinder's plan was to rob as much Dust as possible to "cut" the the security in Vale. If Dust is on everything since it's the main source of power and the current steel that keeps humanity safe then if that Dust were to go down in huge amounts, like the cops said: "Are they trying to create an army?"

Or better question: Are they trying to slow down an army?

Those huges cargos from the docks. If Team RWBY is capable of doing what they can thanks to Dust, then, imagine what tons of hunters are capable of with all that dust. But what if that dust were to disappear leaving them without ammo? Even with all their training, they would still be at disadvantage. After all, Monty needs an excuse to explain how Team RWBY and friends are going to be the turning points in a war since there should be a lot of hunters out there keeping the peace. It would be stupid if they just said that something else distracted or that they couldn't make it on time. There has to be a solid reason to explain the little security out there. Like Blake said: Something big is happening and no one is doing anything!
