There is no "open border" policy, whether Biden's or anyone else's.
Yes, there is. And criminal gangs and cartels are exploiting it.
There's just an acceptance of the fact that you can't close the border down with minefields and machine gun towers a la East Germany.
Please show me who has advocated "minefields and machine gun towers"? Name him.
Rational people can disagree as to whether enough is being done and, if more needs to be done, how much should that be but you can't just shoot folks down at the border and apprehension brings its own problems with the administration of detainees.
Who is advocating "shoot(ing) folks down"? Name him.
The US Border Patrol has some 19,000-20,000 agents of which 17,000 police the southern border.
The US-Mexico border is 3,145 kilometres long. That, by your numbers, is 5.4 Border Patrol agents per kilometre. Factor in shifts, leave, courses, sickness etcetera and the actual number on duty at any one time is closer to one per kilometre. Granted, some areas are impassable and many popular illegal routes of entry are now blocked by new or improved walls, but it is still a huge task.
And the numbers of illegal entrants has exploded, overwhelming processing sites. Disease and stress and sexual and non-sexual assaults are rising as a result.
Just how many do you think the US should allow to casually saunter in?
There are millions of legal border crossings every month from Mexico into the US.
Nobody is worried about legal entrants. They're fine. It's the illegal entrants causing the problems.
50 national guardsman from South Dakota will make no difference at all. A thousand additional ones from other states will make no difference.
So just give up?
US citizens are suffering because of this. Somebody has to pay the costs of supporting immigrants. Property and violent crime and drug overdoses increase because of this, and not only in border areas.
"Never enough" is no excuse to do nothing.
This is an economic migration and a much smaller one then it has been in the past.
Regardless of the causes, a country has the right to control who is allowed to cross its borders inbound, just as you have the right to control who enters your house. And the current numbers have shot up dramatically over the last few months.
It needs a better solution than some misguided millionaire paying for maybe two additional patrols on a 2,000 mile Texas border.
Yes. It requires the federal government to do its %#@*ing job.
In the absence of that, it falls upon others to do what they can, be those others states or private citizens using legal means.
This is crass politics and more importantly it sets a dangerous precedent when a political faction starts making use of military resources.
What's crass about it?
Lives and property are at risk, and the risk is increasing.
The only "political faction ... making use of military resources" are the states who administer and fund those military resources.
Any crassness manifested is that of those charged to defend the US yet ignore their responsibility.
