If that is addressed to me please address it accordingly.For the Met,which happens to be the subject of this errant officer,the relevant code of conduct is enshrined in ,surprise,surprise, 'The Discipline Code'
and a large Tome called Police Orders. It is restricted to members of the Police Service and if borrowed by officers to study for promotion it must be surrendered on retirement. A smaller version called the IB or Instruction Book is a large but smaller equivalent to PO and every officer is issued with it with monthly amendment pages. Again not for public perusal
