A.This is a serious international incident with two opposing interests involved. One is advocating freedom and a cesation to torture and political murder. The other sells cheap crap at Wal-Mart and arms our enemies. Bush apologized to the representative of the later interest.
B. The woman did not threaten the safety of Hu. She threatened his government's future political viability. There is no other way for a rational person to interpret her "threat". BTW, "you suck" is not a threat either: it is an expression of discontent- you know, per the First Amendment?
She must be released immediately.
