As I understand the intent, the National Guard will primarily be partrolling with Texas DPS in rural areas where the cartel, gang, and terrorist action is.
In previous border security operations, they have been fired upon, returned fire, and driven the invaders back across the Rio Grande.
I am all for defense, but lets not pretend that it will result in more deportations of people turned over to ICE.
If you’re wading across the border and you see armed uniform guards, you will walk up to them (entering the US) and surrender, knowing you will not be deported.
