The success of any major incident coordination requires an organised, professional and methodical approach. The Major Room Incident (MIR) is critical to this coordination as this is where all information is gathered and analysed for response coordination.

Major investigation and public protection has many strands and arms. It consists of:

Major Crime:

• Child abuse

• Child sexual exploitation

• Domestic abuse

• Female genital mutilation

• Firearms licensing

• Forced marriage and honour-based violence

• Gangs and youth violence

• Gun crime

• Hate crime

• Homicide

• Kidnap and extortion

• Knife crime

• Missing persons

• Modern slavery

• Prostitution

• Rape and sexual offences

• Stalking or harassment

• Vulnerable adults

• Operation Hydrant

Public protection:

• Mental health

• Managing sexual offenders

It also has major elements of mental health. The Mental health Authorised Professional Practice (APP) has provided guidance on Police response to members of the public who are experiencing mental ill health, have learning disabilities and mental and emotional vulnerable individuals. The guidance applies whether the police are acting in a criminal justice or health care capacity or in both of these roles.
