Not a Trump fan but by "...rapists. And some, I assume, are good people" he no doubt meant some were rapist not all, which is factually correct. Trump says so much bad stuff that twisting his words only really weakens the opposition case.

That expression clearly implies that MOST immigrants are drug dealers, criminals, or rapists - and that he can only assume that a few of them must also be good people (he can't know for sure that any are, though, he can only assume it - implying he has only seen the drug dealers, criminals, and rapists).
