Message on "Smooth Criminal"?

So, you all know Smooth Criminal. If you hear the Bad album version and compare with the Moonwalker version, will realize that there are considerable differences between the lyrics. But ... why these differences? are they clues?

In Bad album:

So they came into the outway
It was Sunday
What a black day
Mouth to mouth resuscitation
Sounding Heartbeats
Intimidations

In the movie Moonwalker:

So they came into the outway
It was Sunday
What a black day
Everytime I tried to find him
He's leaving no clues
Left behind him
And he had no way of knowing
Of the suspect
Or what to expect
Dr. Murray resuscitation
Sounding Heartbeats
Intimidations

Take your own conclusions ;)
