USCG, FEMA ordered doctor to stop saving victim's life

Hopefully the following incident will generate at least a lawsuit. Dr. Mark N. Perlmutter and another doctor flew in to LA with medical supplies and made his way to Louis Armstrong International Airport, where he was asked to look after patients on the tarmac:

In the midst of administering chest compressions to a dying woman several days after Hurricane Katrina struck, Dr. Mark N. Perlmutter was ordered to stop by a federal official because he wasn't registered with the Federal Emergency Management Agency.
"I begged him to let me continue," said Perlmutter, who left his home and practice as an orthopedic surgeon in Pennsylvania to come to Louisiana and volunteer to care for hurricane victims. "People were dying, and I was the only doctor on the tarmac... where scores of nonresponsive patients lay on stretchers. Two patients died in front of me.
"I showed him (the U.S. Coast Guard official in charge) my medical credentials. I had tried to get through to FEMA for 12 hours the day before and finally gave up. I asked him to let me stay until I was replaced by another doctor, but he refused. He said he was afraid of being sued. I informed him about the Good Samaritan laws and asked him if he was willing to let people die so the government wouldn't be sued, but he would not back down. I had to leave."

According to FEMA:
"...The voluntary doctor was not a credentialed FEMA physician and, thus, was subject to law enforcement rules in a disaster area."
The Coast Coast didn't confirm the incident but is looking in to it.
On Sep. 2 LA lifted their out-of-state licensure requirements (PDF).
