I saw this headline[0] "UK government urged to suspend export of tear gas, rubber bullets and riot shields to US" and it made me question if American tech companies have any clauses in their contracts which revoke use when the software/hardware is used to repress civil rights.

There have been a lot of videos of journalists with identifying gear on, beaten by police officers. This alone is a gross violation of rights.
