Itโs all very formulaic the clues conveniently come along as needed but serious plot holes all over the place. Also we are supposed to believe that 15 cops devote 100% of their time to ONE case (one ridiculous scene has the head cop complaining about budget pressures thatโs a good one). The cops in charge dutifully instruct their underlings to check CCTV cameras in the vicinity of the crime scene; I suppose otherwise the junior cops would never think of it.
