Yes, they were wrong. I just did a Google news search and they're all saying that Alito voted along with Ginsburg and Stevens instead of Scalia and Thomas.
See Post 6. If he did vote with the majority, Post 6 makes a lot of sense.
BTW, thanks for clearing it up.
PLEASE look later in the article.
THERE WAS A 9-0 VOTE EARLIER.
THE 6-3 VOTE CAME LATER THIS EVENING.
Now, as for the details on the votes...why the change...what the heck the votes mean....I DO NOT KNOW.
