On so many levels, the cost of the runaway violence can be immeasurable. It has struck a blow to the city's psyche and national image and taken an emotional toll on survivors, the families of those killed and the larger community. Even the financial costs can be hard to fully tabulate. Taxpayers are sure to foot the bill for much of the hospital care for the thousands shot as well as the cost of law enforcement, including nearly 1,000 police officers being added to the department over the next two years.
