Congress government who was in power for last 10 years tried their best to prove his alleged "inaction" for stopping the riots for really 10 years with full state machinery in action. Did they find any evidence against him with all sort of "Special investigation" for these years ?
Supreme court has declared him not guilty of any alleged involvement & inaction. Many people has been convicted for their involvement in Gujarat riots ( including Hindus & Muslim)... You also forgot to mention that nearly 300 Hindus ( many died in police firing) along with 1200 Muslims died in these riots.
