Last paragraph sort of sums it all up.

"I will never be able to sing `We Shall Overcome' quite the same way again," infectious-disease specialist Dr. Ruth Berggren wrote.

A day earlier, she had been at the emergency room doorway as her husband, a doctor at another hospital, tried to help evacuate patients by boat. Shooting broke out, and Berggren was nearly stampeded by people running back inside screaming, "Sniper, sniper!"

Berggren was also unnerved by armed, nervous hospital security guards, an overwrought prison guard watching a patient, and a jumpy Marine who went for his gun when startled by her husband.

"I was never afraid of wind, water, fire, hunger or disease," she wrote. "My moments of fear came when I was confronted by agitated, fearful human beings bearing firearms."
