Good night! We can't possibly be talking on this level! No one is talking about using Predator Drones outfitted with Small Tactical Munitions to kill border crossers. Such talk is so extreme, I haven't any words for it. I would be embarrassed.
Are your border patrol guys supposed to write them a ticket on the spot with instructions to show up in court, or maybe they are going to shoot them.
Once you get past the ticket part, how you shoot them might be meaningful ~ Hellfire missiles work much better than bullets!
It's like the questions you face when selecting a guard dog for your family home. Do you think a little Bijon Fries will do the job (they don't even bark loud but they will jump up on your bed and lick your face until you wake up), or do you prefer a pit bull that can grab and hold a burglar and hold him on the ground ~ by the throat?
Think of what the burglar will make of your decision!
Think of what the dog will think of it.
Think of your family.
