So - the US government has built enough built interstate fences to put almost 48 chain link fences one behind the other at the Mexican border. Factor in all of the concrete used per mile of road and you're talking some serious barriers. Therefore, every time someone says that we do not have the resources or logistics to build a border fence, they are talking a line of utter BS.
The labor should be free,every illegal alien should have to work off his offense by spending three days building the wall. Hell! if the courts object we could pay them minimum wage.
