text: if we build gun towers every few hundred feet along the south border; do you think we will still need a fence?   yes.  with just the towers there will still be many who will or will attempt to cross and there will be a lot of shooting and then i believe we(the usa) will be blamed for a lot of carelessness, etc., and the whole thing will blow up in our faces in the global community.  best to go ahead and do it right to start with and put up a fence.  the costs?  no much considering the costs of those who died on 9/11 and the money we're spending to rebuild iraq.  what about stopping the terror right here at home.  it is the least we can do to help show our young people in iraq we are doing our part here. janie
