Don’t know why we don’t just do two 14 foot chain link and concertina fences with 60 feet of land mines between them.
All lethal force elements are prohibited by the requirement for safety of the CBP Officers who must patrol the Enforcement Zone.
Also, the great bulk of current border crossers are not dangerous criminals, but just regular poor folk. Non-combatants.
During a second month of a Democrat administration the land mines would be disabled, and the following month the chain link fence would be abandoned to the will of the invaders.
We need something more difficult to disable.
