host: todd ruger, do you have thoughts on that? immigration almost immediately came up when it was found that the students involved in the boston bombings, for instance, were here on student visas and the like are is -- like. that is part of that discussion. as far as the other part, the selective service, i am not sure how that fits into the civil rights issue. dot: a tweet says this -- these laws only protect u.s. citizens? guest: that is a great question. i would say, no. i mean, i would say no, they do not only protect u.s. citizens, that there is -- for instance, a company could have a discriminatory policy on hiring or a discriminatory policy on who they rent apartments to. if the department can show a pattern or practice of the discriminatory behavior, which is one of the things they have ,eally tried to focus on pattern of practice, then they don't have to prove, for example, that that policy of a racial discrimination in housing was always followed but that if there's a policy there, then then it is a violation of rights.
