Well, that's what one of the signs in this picture says:
Am I surprised? Absolutely. Not about BYU students opposing torture -- that should be a no-brainer I hope -- but rather that BYU students are openly protesting a decision made by the board of trustees, which includes the first presidency of the LDS church. (For those who aren't up on the latest Mormon news: they invited Dick Cheney to speak at the BYU commencement.)
I don't think it's so much that BYU has changed as it is that Cheney has just done too much damage for anyone to want to honor him. So apparently some students, faculty, etc. have planned what has got to be the world's politest protest: an alternative commencement.
Why do I call it polite? Because it's not even competing with the regular commencement -- they've conveniently scheduled it after so everyone can attend both...
