if elected, i will fight to change the national motto from 'e pluribus unum' to 'report suspicious activity.' (i will just point out, once again, that a wal-mart superstore, or a big public high school, cannot be secured. if terrorism were common here, these places would cease operations. think about all the vehicles that pull up, the deliveries, the trash. think about how many people walk in and out, etc. you cannot have institutions like that in a terrorist world.)
honestly, i don't think you can really secure an airport either. but while a city might have one or two airports, there's a wal-mart and a public high school in every suburb and small town. they have to operate relatively cheaply or they can't operate at all. you're just not going to have DOE screeners reaching into the underwear of every american child, every whitetrash christmasshopper, etc.
