Love Dawn and Billy!
Actually, even if there is no evidence of Meena's murders, she would surely go to jail anyway for kidnapping and trying to kill Manpreet and Vinnie, kidnapping and trying to kill Billy and Dawn, shooting Layla and assaulting Harriet and the limo driver. That should be enough alone to send her to prison for at least 20 years and there is no way she can wriggle out of any of that.
