"He (GOK) says it would be understandable if it were established that Rawat knew of the crimes and did not do anything to stop them, but that this scenario has not been established."

Is there a typo in there somewhere?  A misspoken word?  Surely you don't mean to say that GOK 'says it would be understandable if it were established that Rawat knew of the crimes and did not do anything to stop them, but that this scenario has not been established."

'Understandable'....by who?
