Right or Wrong?

Why would Vivek and Anandi need to dig up Rasika's past? Normally in case doesn't both the prosecutor and defendant need to provide their history and past criminal records (if any)

Yes Anandi and Vivek can make an extra effort but even Rasika would legally need to provide all the information regarding her past...right?

Police said that the boy who sold kerosene has refused to give statement...is it possible in reality?...isn't police strict in collecting evidences? Police tend to use brutness (no offence to anyone) while handling the matter of evidences so how come the teastall boy has an option to give or not give the statement?

Aren't matters against IAS officers (specially collectors) handled with strictness by police becoz fo their power and status? Rasika said that Shiv is a Collector and can use his power to get out of it but here everything is taken lightly by investigators and we see a loss of improtant tape...so what is the truth...Do police handle cases against powerful govt. officers properly or do they take it more lightly as the person in question tend to lose the status of it's job for time being

I'm a bit confused about these certain points so can anyone explain it to me...thanks in advance
