I didn't expect it to be hilarious. No wonder it went viral.
But as someone else pointed out, the coup may have happened in the middle of the night at ~4am or so. Is this really showing the actual coup, or just the aftermath?
I agree that a coup doesn't happen instantly - but this video has captured a unique moment of history if it's showing military forces bloodlessly capturing a government checkpoint. On the other hand, if it's merely showing military vehicles passing through a military checkpoint? There are probably hundreds of videos showing that.
