           | From the TPM follow-up link downthread: faculty at IU were
           | notified more than a week before the raid that he'd been

         | Is it typical for the media to write stories when spies
         | surreptitiously sneak out of a country?
         | 
         | I speculate this guy was long gone before the feds kicked in
         | his door. Assuming he and his wife were indeed spies of course.
         | Right now we cannot confirm or disconfirm that, but the
         | narrative fits it so far.

         | Do you have any sources that this guy was vanned, besides the
         | very reliable Ars Technica comments section crying about
         | 'fascists' and random schizos on BlueSky?

       | 
       | >The China Initiative was a program by the United States
       | Department of Justice to prosecute potential Chinese spies in
       | American research and industry, in order to combat economic
       | espionage. Launched in November 2018, the program targeted
       | hundreds of prominent Chinese-American academics and scientists,
       | of which an estimated 250 lost their jobs. Many more had their
       | careers negatively impacted and the prosecutions also contributed
       | to at least one suicide.
       | 
       | >According to a Bloomberg News analysis of the 50 indictments
       | displayed on the China Initiative webpage, the program had not
       | "been very successful at catching spies." Most of the cases
       | listed by December 17, 2021, involved individual profiteering or
       | career advancement by the accused, rather than state-directed
       | spying. Despite this, many of these indictments portray the
       | alleged crimes as for the benefit of China. Seton Hall University
       | law professor Margaret Lewis described this as "a conflation of
       | individual motives with a country's policy goals" that has led to
       | the criminalization of "China-ness."
