One big problem here is that your ability to insist on your 4th amendment rights varies considerably. The further you are from all of affluent, straight, white, and male the more likely it is that you’ll experience pressure or retaliation if you persist in not cooperating, and in extreme cases that includes illegal detention, violence, or fabrication of evidence.

If your life is a repeating story of having to situationally decide where you’re likely to fall on that scale, you’re probably going to acquiesce because it’s the least stressful option – especially in this case where the easiest retaliation is almost unprovable by “accidentally” making you miss your flight.

There's also almost no recourse even if your rights are violated. If you are lucky any evidence gets excluded from a future trial. But what about some remedy? It is outrageously difficult to sue individual state police or state police departments. Federal agents are even more protected, with Bivens being slowly crushed into nothingness.
