Another Congress mass murderer escapes justice

Someone said the guiding principle of the Indian penal system was that a thousand guilty can escape but one innocent should not suffer. I'm not sure given the rampant corruption running through the socio-economic-political system that this should be the corner stone. Probably few who are the grey area should be punished to warn people observing as well as for future generations to learn.
One such example is the case of the 1984 Sikh riots where thousands of innocent Sikhs were murdered by rampaging mobs urged by the Congress after the death of Indira Gandhi. The same Congress whose leader termed the massacres as

the Earth shakes when a big tree (Indira Gandhi) falls

Here's one of the accused who escaped from the clutches of justice, probably because his party is in power and managed to control the wheels of the law from moving.

Mr. Jagdish Tytler along with his party colleague Mr. Sajjan Kumar are among the main accused of planning and leading the mobs to kill a few thousand Sikhs in New Delhi. Now the CBI after doing an investigation of decades comes back with this enlightening conclusion

that it did not have sufficient evidence to prosecute the former Union Minister, Jagdish Tytler, in a 1984 anti-Sikh riot case.

If Hitler was tried in the Indian judicial system, probably he could've escaped any blame for the Holocaust.
