The one saying he was faster than ever in that sector?

If you have a video of the incident, it's easy to understand that not all corners in that section are not flat out. You have to step on the brake at some time to take a corner you know. This is why sector time is used more often than not to determine if a driver really slowed, or if he conveniently lifted when he was taking a turn, which is what you do to take a turn.
Button didn't lift. Simple. He was flying and he saw the yellows. Nothing substantial to say any lifting was done. All we have is video and sound and sector time.
but this is the "unsafe" hamilton according to you: http://vimeo.com/31262768
