Deroy Murdock: Under Biden, our southern border has become a crime scene

President Joe Biden’s "come one, come all," promises and policies have turned the U.S.-Mexico border into a humanitarian catastrophe, a public-health calamity, and a national-security crisis.

The border criminals include every illegal alien who invades America without permission. They undermine U.S. sovereignty, fleece beleaguered American taxpayers, and mock millions of immigrants who arrive legally. Foreigners who breach the border without passports violate ​U.S. Code § 1325(a) — Improper entry by alien.
