Those Indians might change their mind about the wall when they are the only point of egress.
Put walls around the reservation and leave a opening at the other end so you can funnel the illegals to one point and collect them there. Just let them walk across the reservation.
I was thinkin the same thing
I have heard that some of them are reconsidering.
I think the problem is that the Cocopah live on both sides of the border. The wall would split their territory. Still, where there is will there is a way.
Didn't P. T. Barnum have a sign "This way to the egress"? (This was to get customers moving along instead of loitering--people didn't know what "egress" meant and assumed it was something exotic to see.)
