They were news helicpters hovering in place over some story, it happens 10 times a day in Los Angeles. I've seen them hover in groups like thes for up to 30 minutes before. They cover ABC, NBC, CBS, KTLA, and several other local news channel in LA, 9,11, and 13 local news all have helicopter cams. The one circling was most likely a police helicopter.
Sorry, no cigar on this one.
