"What the knock-and-announce rule has never protected...is one's interest in preventing the government from seeing or taking evidence described in a warrant. Since the interests that were violated in this case have nothing to do with the seizure of the evidence, the exclusionary rule is inapplicable," Justice Antonin Scalia wrote in the majority opinion in Hudson v. Michigan (04-1360)
Exactly right. Can you imagine Sandra going along with something like that? No, when she gave the originalists a victory, she always refused to join clear statements on the law, only narrow ones that refused to say anything and left her wiggle room to side with the lefties later. This is the first of many decisions in which Alito will make a very important difference, not just in the line-up of the vote, but in the quality of the opinions.
