Very Strange UFO Sighting in Garden Grove

I have found a very strange UFO video that isn't normal you see a lot of Government Officials and Police that are ordering people to clear the road as they make room for VERY heavy machinery. They use a loud speaker to do this. The police are very rude, and do not want anyone close. There is even a part where you see the police officers wearing masks as though they are dealing with something thats radioactive, or a biological weapon of some type. Is this really going on in all of the cities of the world? Please comment if you have seen anything like this, this situation has really sparked my interest. Share this video with as many people as you can, so that we may inform people. THIS IS NOT A FAKE VIDEO....Prepare to be amazed. Now for the video...
