In 19 three, when chapman took over the i n s, the cost of crossing the mexican border was effectively zero. By the time he left in 19 77, it was not. In 19 86, comes the imigration reform and control act, which militarizes the border. And then to day with the attorney general of the united states, sometimes sounds like commandant jefferson sessions, i have put in azero tolerance policy for illegal entry on our southwest border. If you cross the border unlawfully, then we will prosecute you. Is that simple?
