> Figure about 10-15% of people are innocent in criminal cases

Much higher than that in these particular cases, as noted in an article linked in OP:

> A recent white paper by a non-partisan organisation of prominent Chinese Americans in business, government, academia and the arts, examined information on nearly 300 defendants charged under the US Economic Espionage Act (EEA) between 1996 and 2020 [...] found that 27% of presumed Asian American citizens charged under the EEA were not convicted of any crimes. In total, the analysis showed that one in three Asian Americans alleged to have committed espionage may have been falsely accused.

And I don't think the feds have had a better record 2020-present.
