I won't believe your allegation that this is untrue unless you show me.
Ah, you don't have to prove what you say, but I have to prove that you're wrong?
Must be nice to consider yourself omniscient.
Anyway, according to Cornell University Law School's records of Supreme Court decisions (available online at
http://supct.law.cornell.edu/supct/justices/histBio.html) you can see that he's written more decisions than O'Connor in several of the years that I checked. I haven't done a thorough search, but considering I came up with several on the FIRST other justice I compared him against, I would say that it's highly unlikely that you're correct.
And after looking at only four cases, I found one - Virginia vs. Black - where he did not agree with Scalia. This equates to a percentage of 75 versus your claim of 90%. So, again, I find your claim that he just "rubber stamps" everything that Scalia says to be highly unlikely as well.
So, are you gonna come up with the cold, hard numbers (and a few links) to back your claim or not?
