Amazing videos of Meteor in Russia!

I like to question everything ... and I seriously question to what degree NASA might be saving face in coming to such a quick conclusion here. I am skeptical of the prevailing authoritative "answer" that has been disseminated by most major media outlets worldwide.
There were numerous fireball sightings being reported in the hours before and after. Were those not related either? Has NASA mapped the trajectories of all of those meteors as well? To not seriously analyze this further, and explore all of the possibilities in this 'mere coincidence' here is not even rubbish science to me, it is the absence of science.
I am perplexed by just how quick so many have seemed to be in dismissing the possibility that these two hunks of matter may well be linked in some way (perhaps going far, far back in time). Maybe they are not linked ... but to claim to know so quickly? It reeks of arrogance.
This is not to rant about NASA, as I am a big admirer of all they have accomplished and continue to discover as a group of many, many dedicated individuals. I am in awe of so much of it. But, they have had problems over the years with politics and bureaucracy as well, it is no secret. I am not stating here that I think there is some conspiracy or coverup. It just sounds a bit more like ineptitude mixed in with embarrassment than anything else to me right now. I surely don't have the answers. But I just wish that the current authorities that be could exercise a little humility here and there, and acknowledge that perhaps they don't exactly know either.
Most scientists seem to agree that it is important to do one's best to exhaust all possible scenarios ... and I do not feel as though such careful scrutiny has been applied here in this particular case, where a conclusion was doled out almost immediately. If humanity is indeed going to attempt the planning of any truly long-term goals for the betterment and sustainability of lifeforms on Earth, then it seems that an improved analysis of such objects might be in order.

Like I said it's debated right now. But there has been some increasing meteors during this time. Especially with N-S paths and being very bright.

Regarding other fireballs at the time. There is a video of a bright evening fireball over Russia (in fact, only about 700 km west of Chelyabinsk!) on Feb 12. But it clearly fell at a very steep angle, so its radiant was most probably in the northern celestial hemisphere. Not related. The Feb 15 Cuba meteor is very dubious with no videos and very few (if any) eyewitness reports. At its supposed magnitude, it should have been seen over a very large area by many people. The Feb 14 Japan fireball (which is not really very large anyway) has a different orbit, although both are Apollo-type orbits with aphelia in the main asteroid belt. The Feb 15 California fireball (which is even smaller) requires a slightly more detailed analysis of the video and eyewitness reports, so not sure about that one.
There is, apparently, at least one confirmed Near-Earth Asteroid and meteorite-dropping fireball association: http://www.spmn.uji....2NY40_MNRAS.pdf

Evidence is growing about a new meteor shower. The Russian event could well be tied to this since they typically have a North to South part over the North pole.
In fact there are many, many showers not yet confirmed.

"But some YouTube-aided detective work suggests that the meteor's parent body belonged to the Apollo family of Earth-crossing asteroids, whose elliptical orbits take them farther than one Earth-sun distance (about 93 million miles) from our star at some point, researchers said."
This one does appear to be an isolated rock at this time.
