Okay, you are correct, in general, about a broad sweep being illogical. OTOH, if the President's main concern is our safety, as he keeps saying, and if we are to believe that his concern is to protection ALL Americans, then certain actions/steps must be taken to back up his concerns. Merely checking people at airports does nothing to effect the safety of all Americans; it's limited to particular people in a particular environment (i.e., those traveling on planes or those who could become possible targets of planes). Taking only a particular action (checking for illegals or bombs at U.S. airports) makes his argument of "protecting all Americans" an absurdity on its face. Illegals can and do enter America at our borders, by the millions, and are, therefore, able to get to U.S. airports, ride U.S. busses, get a hold of forged U.S. documents allowing free travel throughout the U.S., outside of airports.
