Undisciplined use of the sprays out of frustration is no substitute for crowd-control training. Drenching protesters with spray is no contingency plan. Every cell-phone user in sight became a wily tactician and forward observer. Many, many times, protesters confronted the lawbreakers and ran the punks off. Money issues run throughout the review.
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.
