I'm saying we have absolutely no concrete statistical data, and in the press we have many cases where law enforcement has been deliberately negligent in order to deport people who were here legally. We can actually see them deliberately trying to avoid doing the things you would do if you wanted to establish the people you were trying to deport were here illegally. So it's fair to say, until we have some evidence that these people were here illegally the sensible thing to do is to assume they are innocent.

It's also kind of a problem to say "Oh well, we've got no concrete data, let's continue to let them deport whoever they like and shoot anyone who gets in the way".
