While there is little hope of a FENCE stopping this influx There are better solutions.
These solutions take some amount of agreement and diligence by the folks that would be responsible.
I would think that a concerted effort to protect our borders would also protect them from smuggeling.
It is going to take the co-operation of a number of agencies--WORKING TOGETHER-for a common goal and with due diligence to accomplish all of what we wish.
These agencies should, in my opinion, be directed to prioritize their efforts towards the same goals. I think we have the laws necessary to stop illegals from entering if we would all work together to enforce the laws we have and then pass laws that would allow these agencies to plug up the loop-holes.
I would enjoy the armed forces to be deployed to patrol our borders, but this may take a draft in order to have the forces necessary to do this.
