Mitt Romney Billed $10,000 By Newport Beach, Calif. To Cover Cost Of Officer Overtime

What a complex question. If you create the expense by what you say and do, then perhaps the bill is in order. If you have a reasonable expectation that this will happen, or should have had such an expectation. On the other hand, if a town, anticipating trouble spends a bunch of money for something that turns out not to have been needed or that a reasonable person could have concluded likely would not be needd, then I think the local government pays the bill.
