Q

1: Use of Force

Explain the relationship between the ECHR and the responsibilities of Police Scotland

A

Human Rights Act sets out key provisions in the following articles:
Article 2 - Right to life
Article 3 - Right to freedom from torture
Article 5 - Right to liberty

Police officers must balance the above against the need to detain and arrest offenders. The PLANE mnemonic helps to set out the best way to approach this.

Q

2: Conflict Management

Stay Safe Principles

A

The deployment of AFOs should only be authorised in the following circumstances:

Where the officer authorising the deployment has reasons to suppose that officers may have to protect themselves or others from a person who:

  • Is in the possession of a firearm or lethal weapon
  • Is otherwise so dangerous that deployment is appropriate
  • As an operational contingency in a specific operation (based on threat assessment)
  • For the destruction of animals which are dangerous or suffering unnecessarily

General tactical options to be considered:

Waiting
Mitigating action
Observation
Investigative assessment
Containing the area
Communication
Decisive action

Consideration for the ECHR at all times (particularly Article 2)

Stay Safe
Use the National Decision Model
Do not approach unnecessarily
Use cover
Consider safe approach / escape routes
Consider the safety of others
Wear correct PPE

A

Security - When there is immediate danger to any subject
Attack - When officers are under attack
Flight - When the subject is trying to flee
Excessive - Repition - When obvious that voluntary compliance isn’t happening

The attitude cycle

A

Your manner
Affects their attitude
Which in turn affects your attitude
Which affects their manner

17
Q

2: Tactical Communications

The chemical cocktail

A

During conflict the body releases several chemicals

Adrenaline
Endorphins - Painkillers
Dopamine - Neurotransmitter to boost signals
Noradrenaline - Causes vasoconstriction (blood flow to the core)
Cortisol - Hormone which reduces effects of shock

Taken together these chemicals can provide the following:

Increased strength
Increased pain threshold
Increased awareness and focus
Muscle tightening
Visual slow down
Tunnel vision
Post incident fatigue
18
Q

2: Tactical Communications

Compliance and Submission Signals

A
Open body language
Relaxation of muscles
Signs of exhaustion/sweating/being out of breath
Falling onto knees
Not always true in all cases
19
Q

Drugs/alcohol

Q

4: Medical Implications and Mental Health

Explain the dangers of positional asphyxia

A

Likely to occur when a subject is left in a position that restricts breathing for an extended period.

Risk factors include:
Age
Health
Weight
Alcohol/drugs
Exhaustion
Respiratory illness
Symptoms include:
Cyanosis
Agonal breathing
Beavioural changes
Panic
Stating that they cannot breathe
22
Q

4: Medical Implications and Mental Health

Dangers of acute behavioural disorder, and control measures

A
Agitation/aggression
Abnormal physiology
Delerium
Abnormal stregnth
Abnormal pain tolerance
Abnormal stamina
Non responsive to commands

Recognise that ABD is a medical emergency and take appropriate action
If possible, in contained spaces, allow the subject space to move around
Seek to restrain and control the subject with the minimum necessary force (verbal de-escalation unlikely to work) and then move to a seated, kneeling or standing position to prevent positional asphyxia
Speak in a calm fashion and explain what is happening

23
Q

4: Medical Implications and Mental Health

Dangers of neck restraints

A

Pressure on the front of the neck restricts breathing
Pressure on the sides of the neck restricts blood flow to the brain
Damage to the trachea, thyroid cartilage

24
Q

4: Medical Implications and Mental Health

Dangers of handcuff neuropathy and control measures

A

Damage to the main nerves in the wrist
Bruising and/or cuts
Sprains/strains to the muscles
Breakage of the bones

Important to check the correct tightening of the cuffs has been applied, that double locks have been applied, that wrists are positioned correctly and not bent back, and that when moving the subject around the wrists are protected.

Struggling/resisting as well as falling etc, can all lead to these kinds of dangers too

25
Q

4: Medical Implications and Mental Health

A

Twitching/spasming of the eyelids

Damage to organs - kidneyes, spleen, groin, bowel
Damage to muscles and soft tissues in extremities, broken bones etc

Stick to green areas and avoid red areas

28
Q

4: Medical Implications and Mental Health

Mental health guidance

A

View and respond to subjects suffering from a mental health issue in terms of vulnerability wherever possible.

30
Q

Avoid standing directly in front, or behind, a subject.

31
Q

4: Medical Implications and Mental Health

Zones and tactical positioning
