None of us have any idea of what is going on with China in the background. I include myself, of course, among those who don't know. I have read the word "betrayed" applied to the president in this thread and it is unwarranted, at least without some proof, IMO. Who knows what sort of deal on terrorism, oil or something else that is being negotiated behind closed doors.
I have disagreed with President Bush on occasion (education is a good example), but one thing I have seen from this administration repeatedly is allowing opponents to climb out on limbs and then sawing them off.
In any event, it was right to arrest this lady for disrupting a state event, whether you agree with her or not (and I do).
