I'm sorry, but this is just silly:
But hey, logic is overrated.
- To start off, the building at the start probably houses people who are witnesses in major crime investigations and need protection. Also, there's over 300,000 million people in America, the idea that a little building like that could house even a small percentage of American's is crazy, even if it were six of them like mentioned in the video.
- As for the coffins, it's probably something as simple as a contractor getting a deal from a politician as "favor". It's also not that many coffins, just look at the devastation that happened in New Orleans. Also, if they wanted to mass murder us, I doubt they'd care about properly burying us in coffins; that's what pits are for.
