I recvd a call from a friend telling me to run outside my apt complex when I noticed 30 craft in the sky. I ran to a police officer and a security guard watching the event. When I was talking to them they appeared to be frightened and I watched these 30 lights craft hang in the area for approx what seemed to b 20 mins. Then they dispersed faster then any craft I have ever seen in different directions. 2 or 3 of them returned for a few seconds and disappeared.
