Police can only spend what the politicians provide. Here is another spot for a close, candid look. A sound plan to have the Washington National Guard in town on standby was never fully developed for lack of money. The same with help from outside law-enforcement agencies. Emergencies would trigger the call-ups, which is what happened.
Contingency planning done on the cheap is no contingency planning at all.
Hearing from the police is a good start. Additional insight and balance is needed from the crowd-control experts and the council investigations.
