Well they do it with the wired fences:
"Gov. Greg Abbott, a staunch Republican and opponent of President Biden’s immigration policies, accused the Biden administration of cutting through razor wire in an X (formally known as Twitter) post in September.
"Texas installed razor wire in Eagle Pass to stop illegal crossings. Today the Biden Admin CUT that wire, opening the floodgates to illegal immigrants. I immediately deployed more Texas National Guard to repel illegal crossings & install more razor wire," he posted on X."
A federal judge temporarily barred the federal government from removing or cutting razor wire Texas authorities have placed in areas near the U.S. - Mexico border.
