An army of police officers just descended on the area around Emory University in Atlanta, Georgia, after reports of an active shooter — and social media videos capture the sounds of rapid gunfire.

Emory University officials sent out an alert at about 5 PM local time., advising students to “RUN, HIDE, FIGHT. Avoid the area.”

One of the focal points of the shooting is a CVS store, where CNN got footage of what appeared to be a wounded uniformed cop being carried out on a stretcher into a waiting ambulance.
