There's one thing we can do, other than just wring our hands over the China holocaust, still in process. We can protect the students here.
Now they are being photographed, spied upon, tracked down and threatened by undercover operatives of the ruling murderous junta. Retaliation is threatened when these students return to China, and/or immediately against their families now in China.
But the Chinese students and the Chinese-American community know these infiltrators, and they can be apprehended and deported. The attempt to bring the China wars into this country can be stopped at the water's edge.
Our laws are clear on the matter: The Chinese students (as well as all aliens) enjoy the full protection of the U.S. Constitution while here. International law is clear on the matter: Representatives of a foreign government have no right to carry out acts of political repression in another country.
