Why is she not arrested?

Natasha is a criminal right(burning down someone's house is not legal😉)?? So y r the cops not arresting her?? No one knows who Natasha is, but everyone knows that people contact her thru a post box, so all the cops have to do is, keep an eye on the post box and who ever opens it gets arrested, or they can even set up a trap by sending a mail to tht post box acting like a woman in trouble and when Natasha goes there they can arrest her.

And it is no secret that Natasha goes to Kali Mandir at mid night, as that girl who was waiting for her there knew, Natasha goes there, so can't the cops watch tht place, and can draw up at least a list of suspects??

I know!!! couldn't they come up with anything better...They don't even need cops to expose her...Tv reprters and journalist can do it themselves...they are always nosy...this natasha story is really irrtating me..It's not interesting at all
