Because somebody had to say: "Gabi Hernandez, you're under arrest," the success-starved Salem P.D. would probably count this as a "bust." As for the Gabi search warrant, I no longer recall the circumstances that led to her arrest, but if Roman & Co. got a warrant, which was based on "she had a diaper bag and then she didn't," it sounds like one of those only in Salem moments. There are just too reasonable explanations for Gabi not having the bag after Tricky Nicky was shot. Perhaps, Roman said to the judge: "Please your honor, I've got a hunch on this one. Give me a break. Everyone is laughing at the Salem P.D., and we need a big arrest to shut them up."
