Build the fence first and then try for the immigration bill. If it’s a trust issue then have congress pass a bill guaranteeing they will visit the immigration issue after all 800 miles of fence is built.
Not just the fence — after the fence is built use all the technology available to make a virtual fence so that INS can view the whole length and get agents to areas where they have broken through the fence. We need two fences — one to the north and one to the south.
