These are just indiscriminate sweeps being justified by the 100 mile border exception.
A CBP officer could yank you out of your car on the cross bronx expressway and then search the vehicle top to bottom and your legal recourse would be to hope that CBP feels bad and reimburses you somehow, you would be owed no legal damages because it isn't illegal.
This isn't hyperbole, it's actually that ridiculous.
From the Congressional Research Service: (https://fas.org/sgp/crs/homesec/RL31826.pdf, page 8)
> Under the “extended border search” doctrine, government officials may conduct a warrantless search beyond the border or its functional equivalent if (1) the government officials have a reasonable certainty that a border was crossed or there exists a “high degree of probability” that a border was crossed; (2) they also have reasonable certainty that no change in the object of the search has occurred between the time of the border crossing and the search; and (3) they have “reasonable suspicion” that criminal activity was occurring.
In online reporting, there is often significant confusion between the "Extended Border Area" (ie. the 100 mile zone) and the "Functional Equivalent of the Border" (ie. an airport customs zone).
The only new thing is the increased size of the sprawling bureaucracy of Customs and the Border Control, and the increased tempo of operations.
The real problem is the growth of executive power and the supine nature of the Congress and courts. This particular issue has attention due to the disgusting conduct of the current administration. We live in an era where the President believes that he posses banana republic like presidential immunity and executive privilege.
Driving in Queens doesn't give CBP the ability to pull you over and rip apart your car. Picking up someone at JFK may give them the ability for them to do so on the way home.
