Well, if it gets overturned on the basis over preemption, I’ll be mildly surprised, but not shocked to my very core. I regard the preemption argument as wrong but tenable.
If it’s overturned because of some Equal Protection-type claim, I will humbly and sincerely eat helping after helping of crow.
And what about the reverse scenario – the law is sustained, and doesn’t produce substantially more claims of racial profiling than existed beforehand?
Will the opponents step up with some, “I was wrong,” statements?
