This police officer put everyone’s fears to rest with a single tweet during ITV’s Marcella
Don't worry, Anna Friel's filing system is not standard practice...

Assistant Chief Constable Phil Kay of Leicestershire Police was watching ITV’s new crime drama, Marcella, a Scandi-noir style detective drama starring Anna Friel, on Monday night when he decided one sequence of events was just too unrealistic to let pass.
Kay took to Twitter, and in one single tweet, won everyone’s hearts while reassuring us that there’s a level of professionalism in policing.
Can I just reassure the public that detectives don't routinely have previous murder case papers upstairs in a cupboard #Marcella
