A murder has occured with them present, obviously they will be questioned ..and not only TRPTI POINTED TOWARDS VIRANIS, SHE WROTE THE KILLER IS A VIRANI TOO ( and without malice, we din't see she doing it for revenge or to frame viranis, the dying person honestly said and thought - "Since i can't live , i sud write down my killers name for all to know", and she wrote THAT IT IS A VIRANI) ..and viranis were like thnreatning ACP like a bunch of jerks - why you are asking us, giving ilzaam, tripti's hand written note is proof quite..and TULSI SAYING NO VIRANI can kill .ROFL..WHERE AS SHE ALONG WITH NANDINI BOTH HAVE KILLED, MANY RAPED, MANY DONE MANY THINGS.
These people need a good third degree treatmetn now, as asking in civil way them is useless. Co-operate with country's law liek responsible citizens not argue like barbarians uselessly. And its not without reason you are suspected.
