Health care and public safety have come a long way since the Spanish Flu epidemic of 1918, but what hasn't changed is how America will likely respond to such an outbreak. That means that public order personnel on every level are very likely to face a multitude of threats emanating from a health debacle—threats not only from disease but also those created by a panicked public and a criminal element determined to exploit the situation.
The multitude of demands that may be faced by American law enforcement during a flu pandemic will change the way that police departments do business. For example, normal law enforcement patrol duties may have to be suspended, presenting predators that somehow avoid becoming sick themselves with unprecedented opportunities for crime.
Many municipalities have planned and exercised disaster response plans. However, the biggest challenge will be preventing panic among an anxious public and soliciting its cooperation to preserve the common good.
In other words, will 21st century Americans accept the same draconian but necessary measures and restrictions on their liberties as the people of 1918? Probably not. The post World War I population was used to sacrifice and doing without. They were disciplined and understood that quarantines, facility closures, restricted travel, food shortages, and reductions in services were necessary.
Back in 1918, trains would not board passengers and towns denied visitors admittance without proper documentation. Funerals were limited to 15 minutes, gauze masks were universally worn in public, and stores could not hold sales. Heavy fines and punishment were levied against those citizens that violated these decrees. Yet despite such harsh measures, Americans generally accepted government authority. This collective spirit allowed public health officials to intervene and implement their plans and few citizens criticized the effort. People even volunteered to fill the vacuums created by succumbing doctors, nurses, and police officers.
