Just put up a roadblock and tell them to turn around....

Why is shoot to kill an option? If they're not applying for citizenship legally, that's no reason to kill people. Just like if someone applied for a passport and was given a counterfeit one, you don't kill them.

I think people are too afraid of something that happens all the time. Border patrol knows what they are doing. Theres no conspiracy with the border patrol and just letting immigrants in. If it's a caravan of 5,000, they'll be spotted.

Stop freaking out.
