I think Scalia’s point is that in the circumstances of this case (controlled delivery) there is probable cause to believe that the evidence will be at the place to be searched when the warrant is to be executed, and he emphasizes when not if. I believe he even italicized this point in the opinion. So the standard is still probable cause, and not the probability of probable cause (what you and I have both called l08;probab2y probable cause.”)
A plinesagly rational answer. Good to hear from you.
