If no additional illegals come into the country, that would stop the flow, which is the real problem.

Wikipedia on the US/Mexico border:

The border's total length is 1,954 mi, according to figures given by the International Boundary and Water Commission. It is the most frequently crossed international border in the world, with approximately 350 million legal crossings being made annually.

There are an estimated half a million illegal entries into the United States each year.

Wikipedia on the Paladin:

Crew:                     6
Effective firing range:  11 mi
Operational range:      216 mi

So to cover the border we'd need 1,954 / 22 ≈ 89 Paladins… but that's an under-count because that would entail butting them directly on the border. We would actually want them back a bit.

c² = b² + a²
11²  = 5.5² + a²
121 = 30.25 + a²
90.75 = a²
9.5 ≈ a

So, we could put them 5.5 mi away from the border, allowing them to cover 19 mi of border; this would mean that we'd need 1,954 / 19 ≈ 103 paladins [103 * 6 = 618 men].
Or, we could put them 9.5 mi away from the border, allowing them to cover 11 mi of border; this would mean that we'd need 1,954 / 11 ≈ 178 paladins [178 * 6 = 1,068 men].
(Of course we'd need logistics to support them: meals, munitions, mail, etc.)

See, securing the border is not as hard as they make it out to be.

Severely punishing employers who knowingly hire illegals, punishing landlords that rent to illegals, banning the sale of real estate to illegals and barring illegals from collecting food stamps, welfare and any number of other social services would go a long, long way towards repelling the illegal invaders. Many would self deport.

Funny... A US citizen caught illegally in Mexico will find themselves in prison and if lucky after some payola deported. A US citizen is entitled to nothing in Mexico - not even the presumption of innocence.

You got it. Good job.

The problems securing the border have nothing to do with logistics.

Securing the border would have been a great use of the trillions wasn’t on the so-called stimulus.

Minefields work too. So do seismic monitoring devices, infrared, and radio emissions detection.

1000 men and 108 paladins. Excellent. We have 40,000 in the TSA, right?
