I want to know the answer to the following question:
Though he urged for demonstrations in Vietnam, Nguyễn Văn Hải was charged with what crime?
All the background I'm provided with is that "A Vietnamese American was deported for planning protests against the torch, while a prominent blogger, Điếu Cày (real name Nguyễn Văn Hải), who blogged about protests around the world and who called for demonstrations in Vietnam, was arrested on charges of tax evasion.". Is that enough to answer the question?
