AMA Request: Anyone in/near Hollywood CA who witnessed the UFOs and helicopters on the evening of July 8th 2012

Hollywood UFO Video

1. Could this have been a movie/tv production?
2. What did the helicopters look like? Police copters?
3. What happened after the video ends? (kind of suspicious to me)
4. Was there any local media coverage?
5. Could they have been lanterns? (but why would a copter circle a paper lantern?)
