Of course not but the BP was doing what it was authorized to do. And, unlike aobrtion, for good reason. Without the checkpoints the border is wide open. If you want open borders go for it but most Americans do not.
The idea that these are Soviet-tyle checkpoints or that it has something to do with speaking out about public policy is childish.
I was employing reducto absurdum, to make a point. Sorry if I didn’t make that more clear. That said, there IS such a thing as “the slippery slope”. You might be sanguine about totalitarian governmental rulings and practices now, but in the future you (or your children) might well be singing another tune.
