I would assume that the actual police have their own traditional methods of being irrationally vindictive, and would not normally restort to DDoS.
Indian police will have a lot of trouble beating you if you live in another country.
Their government might though..
Google Hardeep Singh Nijjar.
Still a lot of trouble.
Those traditional methods don't often work very well across borders like a DDoS does. The post at the top of the thread didn't state whether or not they were based in India too.
