>An officer who purposefully allows a fellow officer to violate a victim's Constitutional rights may be prosecuted for failure to intervene to stop the Constitutional violation.
>To prosecute such an officer, the government must show that the defendant officer was aware of the Constitutional violation, had an opportunity to intervene, and chose not to do so.
Unfortunately the courts have repeated ruled that "aware of the Constitutional violation" means knowing that the exact action being observed had previously been ruled a violation of Constitutional rights. It's essentially impossible to prove, which is one of the reasons we don't see that offense prosecuted.
