I would suggest that they didn't find any "suckers". I would suggest (and the evidence does appear to back this up, and ACORN's attorney is threatening legal action on the basis of this) that what happened was that the people who made the films had tried unsuccessfully for months to find a "sucker" and when they couldn't find any, and in their desperation to smear ACORN, they resorted to falsifying the evidence.

There still is zero proof that things happened the way the makers of the video have tried to make them look, and more than ample evidence that they fabricated the whole thing.

That's not entrapment. That's something else entirely.
