It also offers protection for "persons acting in good faith" as no suit, prosecution or other legal proceedings can be instituted against the competent authority or "any person exercising powers under this Act."

This is not rocket science. KKK operated in similar ways.

The anti-cow slaughter Bill has been drafted in such a manner that cow vigilantes will be granted protection under Section 17. Interpreting the “good faith” clause means that no suit, prosecution or legal proceedings will be initiated against the vigilantes if they can prove that they committed the act in such a manner.

States with stringent laws on cow slaughter have often reported high cases of lynching by cow vigilantes. According to a report of the New York based Human Rights Watch, 44 people in India have been killed by cow vigilantes within a span of three years. The report further revealed that these radical cow protection groups often received support from politicians and law enforcement agencies.
