The volume of patients in need of hospital care led several emergency room physicians on Monday to call for an end to raves at the Coliseum.
Cathy Chidester, director of the county Emergency Medical Systems agency, said Monday that officials treat raves at the Coliseum like a "multi-casualty incident," which she said was similar to planning for a disaster like the Chatsworth Metrolink train crash, which killed 25 and injured more than 130.
