These laws are used to hamstring border patrol. So they have to get off vehicles and ride horses.
The drug cartels running illegals and drugs have spotters in the mountains to watch the border patrols.
The border patrol does not have as easy access ?
Maybe what we should be doing instead is setting aside the entire southern border as a “habitat” and stock it with tigers. With all the illegals crossing there, the tigers’ hunting ground would be well stocked.
