Cosmic Coincidence?

NASA is saying that without a doubt, the meteorite that hit the city of Chelyabinsk had nothing to do with the asteroid 2012 DA14, and that it was just a, "cosmic coincidence" that their arrivals were so close together. I'm sorry, but I find that a little hard to swallow. After all, it's the same scientists who are claiming that an asteroid the size of 2012 DA14 only comes along about once every 1200 years. Even meteorites the size of a double-decker bus are said to be very uncommon. So what are the chances that both these space bodies happened to grace us with their presence within twelve hours or so of each other?

Here's my guess, and let me stress, these are just my "opinion", and not facts in any way. I believe that the meteorite that hit Chelyabinsk was either a piece of 2012 DA14, or at the very least was a piece of debris that's been flying along beside it. Because of it's nearness to the larger mass of the asteroid, scientists missed seeing it. I think this is highly plausible, and let's face it, no one wants to admit that they screwed up and missed seeing something the size of a bus that ends up hitting the earth!

My second theory is going waaaay out on a limb, but why the heck not?! What if 2012 DA14 was actually on a trajectory to hit the earth? I mean look at how much damage that "meteorite" did over the Ural mountains. It only weighed an estimated 10 tons. 2012 DA14 weighs in at a hefty 130,000 tons! The government most likely wouldn't have told us if it had been, for fear of widespread panic. Just a couple of days ago, the United States launched a "satellite" into orbit. What if there had been no satellite and in actuality we'd launched a missile at 2012 DA14 in attempt to make it veer away from the Earth? After the ensuing explosion, a piece of it ends up entering the atmosphere and causing havoc over the Urals. Yeah, it sounds like something right out of a SyFy channel movie, but the fact is we may never know even if that were the truth since the government wouldn't want to take credit for averting a major disaster since there was still collateral damage.
