WTC....the uneven collapse

so we have this video that we have all seen...amazing and dramatic footage of the collapse. Ignore the squibs in the video and watch how the right side of the building seems to get "blown out" or "collapse" faster than the left side:

youtube.com...

They slow it down and you can see that it is obvious that one side is failing faster than the other. Well what does this tell us? There is something that is causing the collapse to act like this.....the weight of the floors above MUST be evenly distributed to cause a global collapse right? it has to be or else the top of the building would have fell over into the street....Certainly one side was not built stronger than the other.

So here we have, in plain sight, evidence that the collapse was not even, yet the whole building collapsed in the same manner. There WERE explosives, there have to be to cause this smoking gun...ehem...I mean anomoly

Here you can clearly see explosives used to sever the trusses from the core columns to outer facade.
