I think that race has to be a consideration, along with other factors, i.e. one way ticket buying, etc., in determining if someone may be a risk to the security of others.
That is where the problem is. Terrorists can buy two way tickets with credit cards. Not a rare possibility. Infact, I can't think of any criterion that will work well on a majority of criminals and exclude majority of innocents. Though I don't agree with you, let us keep race as one factor. What else, please list. Because avoiding this list is avoiding the important question. Do we have any objective criteria today? Remember that all the middle eastern visitors have been background checked (after 9/11) before they are granted visa. They don't get multiple entry visas either if they belong to middle-east. Again please list your criteria.
