Well, if some one wants to get exacting on the English and how the phrase is given, the quote actually has Trump telling them to try not to hurt anyone and if they do, he will pay their legal fees..
It does not say, "but if you do."
It actually says that if they try not to hurt them he will pay their legal fees.
That’s why liberals have taken over public education, and stopped teaching children how to read and understand what they have read. Look around at all the people who have no idea what Trump said, because they don’t understand the English language. They insist he made promises he never made, and they probably believe that, because they were told to. And they vote.
