In addition to the cut of Jin slitting the policeman's throat, they also cut the part where Jin gets back and finds Mei with a dagger in her, cradles her in his arms, and she warns him to turn around. In the movie, Jin comes back looks down at Mei and then they cut directly to a shot of Leo attacking from behind. Maybe this was done because they didn't want Mei's dying to be too protracted. I saw the movie four times yesterday and every audience liked it, except for Mei taking so long to die. The cut was probably made to appease American audiences.

In addition to the throat slashing cut and the cut where Jin cradles Mei while she tells him to look behind him, there is a digital erase on the scene where Mei pulls out the dagger. In the Chinese version, blood pours out of the wound when she pulls the dagger put, but even though Jin tells her the blood will drain, in the US Version you see her pull the dagger out but the blood doesn't pour out. The scene is intact, but they erased the blood pouring out.
