5 said it is trespassing and 4 said it is an invasion of privacy. No one thought it was acceptable.
Actually 5 said it is an invasion of privacy also. Sotomayor said that she probably agreed that it was an invasion of privacy, but she didn't need to reach that issue because it is a trespass.
Alito(!?!?!?!) actually has a fairly reasoned and rational concurrence where he explains the law, criticizes the majority's analysis, and raises issues for future discussion. Wow. What next? Mitt Romney appearing human and less entitled?
