comment on youtube below says "Carl didn't do this. The camera man got bumped. I was there."
Also, I would think if a camera got broken, you wouldn't have video from it aftewards... But maybe i'm crazy.
That's what seemed odd, he turns away, then it was like it just fell. Makes sense if someone bumped into him and he dropped it.
No sound....he turns away before we see what actually happens....this entire thing seems fishy...until we find out what actually find out the whole story we shouldn't blame Carl 100% for this at all.
